The Challenge
In the early 2000s, my PR company Signalroom was approached by a high-end mobile catering collective, Field & Flame. They had secured a pitch at the Glastonbury Music Festival and planned to sell premium festival food — wood-fired pizzas, artisanal burgers, and dishes that were deliberately positioned far above the usual burger-van standards.
The issue wasn’t product or pricing. It was audience fit.
At that time, Glastonbury’s core attendees tended to fall into two dominant groups: the alternative and spiritually inclined festival-goers, many of whom favoured vegetarian or low-impact food choices, and younger, lower-income visitors who were focused on affordability rather than quality. Neither group was a natural market for high-end, premium-priced festival food.
Our brief, therefore, was not to persuade people to buy more upmarket food once they arrived. It was to change who arrived in the first place.
We needed to attract a different kind of festival-goer altogether: a middle-aged, middle-class audience with established careers and disposable income. We had to find ways to help them rethink their assumptions about Glastonbury and turn it into a cultural and social must-do.
This was the first contract for myself and Crispin when I went independent with my own agency. The campaign features in my memoir Confessions of a Professional Conspiracy Theorist.
The Insight: Weaponising Nostalgia
We realized we couldn’t sell the reality of the festival (mud, noise, crowds). Instead, we had to sell an identity. We had to convince them Glastonbury was for people just like them. And crucially, we had to sell them their youth back.
Our target audience grew up on T-Rex, David Bowie, and Blondie. They now owned slow cookers and quietly assumed their festival days were behind them — if they’d ever had the time for them in the first place. Our psychological insight was simple: we needed to make it emotionally indefensible for them not to go — to the point where the only remaining question was, why not?
We reframed Glastonbury not as a youth event, but as a cultural pilgrimage. The appeal was a more mature form of FOMO: not “what am I missing this weekend?”, but “what will I wish I’d done more of?”
The Strategy
Our campaign relied on three deliberate psychological levers.
Reframing the Narrative (Adult Comfort)
First, we had to remove the primary obstacle: discomfort. We reframed Glastonbury as something that could be done properly.
Articles were seeded in Observer Magazine and similar publications under headlines like “Glastonbury for Grown-Ups”, emphasising dry camping, decent coffee, morning yoga, and late-night jazz lounges.
Strategic partnerships with brands such as M&S and Barbour helped reinforce the impression that this was not an endurance test, but a civilised, middle-class pursuit.
Social Proof (People Just Like You Are Going)
We also needed to resolve a typical anxiety: who else will be there? For this audience, the risk wasn’t missing out, but feeling out of place.
By showing that peers — people of a similar age, with similar careers and lifestyles were already going, we reframed the decision as socially safe. Once that perception took hold, not going began to feel less like caution and more like opting out.
The Third-Party Technique (Validation by Trusted Voices)
This was the core lever. Reframing reduced resistance and social proof eased anxiety, but neither could complete the job alone. What ultimately shifted behaviour was validation from trusted third parties.
People do not want to be persuaded directly. Being told they should attend Glastonbury would have triggered scepticism and self-justification. Instead, they needed to see the decision endorsed indirectly by people whose judgement they already respected.
Our task, therefore, was not to promote the festival, but to normalise the idea of going later in life. To make attendance feel culturally approved, socially safe, and slightly overdue.
Once that validation was in place, the tactics could do their work.
The Execution
We ensured that the Glastonbury for Grown-Ups articles were accompanied by carefully chosen photographs of people already admired by our audience — familiar national figures such as Joanna Lumley, Billy Connolly, and Michael Caine. Wherever possible, we selected images showing them in boots and rainwear, creating the gentle implication that they had already attended the festival themselves.
We then identified the trusted voices. For women, this meant the familiar panellists from an all-female TV discussion show; for men, we looked at guests booked on a mainstream radio station with a strong reach among our target demographic. These were not outsiders or provocateurs, but culturally adjacent figures whose opinions carried weight precisely because they felt similar and relateable.
We did not pay for endorsements. Instead, we used a soft-pitch approach aimed at publicists. The festival was framed not as a promotional obligation, but as a reputational opportunity — a chance for their clients to appear spontaneous, youthful, and culturally engaged without trying too hard.
To support this, we supplied publicists with light-touch thought-starters and conversational cues ahead of interviews and appearances. Nothing scripted, nothing declarative — just enough to make Glastonbury feel like a natural point of reflection rather than a talking point.
As a final nudge, we offered day passes to the festival’s VIP areas, supplied by our client, should they choose to attend themselves.
It’s worth noting that the mechanics behind this campaign haven’t disappeared. What has changed is where they surface. In the early 2000s, third-party validation travelled through newspapers, radio, and familiar television figures. Today, the same signals appear across different platforms — influencers, podcasts, group chats, and algorithmic feeds — but the function is identical. The channels have changed; the psychology remains the same.
The Outreach Mechanism
Below is an example of the communication used to seed the narrative without the need for a commercial contract:
To: Caroline Preston, Publicity Prime
From: Crispin de Vere, Signalroom
Subject: Light Touch Media Mention – Glastonbury
Hi Caroline.
I’m currently heading up a quiet little nostalgia-led campaign… The angle is very much about celebrating the festival’s heritage… It’s less about the mud and more about the memories.
We were simply thinking that if Anneka happens to be discussing summer plans, a soft, off-hand mention could be a wonderful, authentic-feeling moment for her audience. Something along the lines of:
‘I nearly said no this year, thought I was past it. Then I thought—when was the last time I did something truly unforgettable?’”
We supplied the publicists with a small set of additional thought-starters — conversational cues their clients could draw on if the subject arose.
‘I thought I was too old for festivals. I was wrong. Turns out I was just out of practice.’
‘It’s not about tents or toilets—it’s about stories.’
“I caught myself saying no to Glastonbury. That’s when I realised—I was dangerously close to becoming sensible.”
The Mechanics of Influence
The success of this campaign relied on what is known as the two-step flow of communication.
Rather than attempting to persuade the audience directly, the message moved in two stages.
Step 1
We placed the idea with opinion leaders — in this case, celebrities and the publicists who managed their public presence. These were people already trusted by our target audience, and whose opinions carried cultural weight without feeling instructional.
Step 2
Those opinion leaders passed the idea on, often indirectly, through interviews, panel discussions, or casual remarks. By the time the message reached the wider audience, it no longer felt like a campaign message at all — it felt like a personal reflection someone else had already had.
This distinction mattered. Messages delivered through advertising invite scrutiny. Messages encountered through admired figures, offered conversationally rather than declaratively, tend to pass unnoticed. The audience does not feel persuaded; they feel recognised.
Because the idea arrived via a familiar, well-liked figure — and surfaced as a throwaway comment rather than a call to action — critical defences were lowered. The thought wasn’t received as instruction, but adopted as insight. In many cases, it didn’t feel like something they had been told, but something they had quietly realised for themselves.
The Result
Within weeks, the narrative shift was visible across national media. Television presenters and radio guests began “off-handedly” mentioning their plans to attend, often using variations of the same reframing lines — not as endorsements, but as personal observations. What had previously sounded eccentric or uncomfortable was now discussed as normal, even overdue.
As this language circulated, the perception of Glastonbury changed with it. The festival was no longer framed as something endured in youth, but as something returned to later — a cultural experience reclaimed rather than survived. Attendance by the target demographic followed, not in a dramatic spike, but as a steady and noticeable change in who felt entitled to be there.
For our client, Field & Flame, the outcome was straightforward. The campaign did not need to persuade people to spend more once inside the festival gates; it ensured that the people arriving were already willing and able to do so. By changing who attended, rather than how they were sold to, we delivered a captive audience with the necessary spending power — and the commercial results followed naturally.
Consultant’s Note
This campaign demonstrates that improving sales does not always require changing the product. Often, it requires changing who feels entitled to want it. By combining nostalgia, social proof, and third-party validation, we reframed a muddy field as a cultural obligation — less a weekend away than a belated rite of passage.
