Ohhh good point @sweetlyfez , a thing about pantomime is that there’s specific call-and-responses. Children are trained to shout things at the actors at specific points, like if someone is creeping up behind a character, the audience all go “it’s behind you!” in a slightly creepily unified chorus. Like, the tone and cadence are always perfectly consistent.
But a thing about the UK is that people a) will show up to the opening of an envelope, b) will make the HELL out of a tradition or ritual. If it happens three times, it’s an official local ritual.
Rituals always contain a tremendous reliance on everyone’s willingness to participate and suspend cringe. Like the panto call-and-response, people are often surprisingly willing to do it.
So you can get a surprising number of people to do bonkers unified things like “hold hands with strangers and dance around a person dressed as a Green Man”. There was a “clap for the NHS” thing in lockdown (cringe, annoying) but people were willing. There’s a local ritual that involves stomping around a local apple orchard, wassailing it, and hanging toast on the branches. Everyone is tremendously engaged and serious about this. Crowds are generally quite willing to turn up and shout unified chants. During right-wing property vandalising outbreaks there were far more people turning up in anti-fash defence than there ever were fash, but what was most amusing about it was that anti-fash brought bands and snacks. Like within thirty minutes of people being outside systematically, there will start being self-organised predictable small Behaviours. When the shed blew down on my allotment, a collection of elderly people righted it and repaired it and brewed tea about it in about 30 minutes, including the time it took to stand around congratulating each other.
You can genuinely say, “turn up at 3 pm to a muddy field, we’re all going to scream at the sky. No, that’s it, literally that’s all I’m offering” and get 100 people in frigid winter to race willingly to a muddy field in awful weather with flasks of tea, alcohol, picnics, an impromptu cricket game, several more guests than you expected, and a really startling total willingness to scream like fools at the sky. Like YEAH SKY SCREAMING TIME. Let’s do it every Thursday at 4!!! And the thing is you’ll find yourself being like “oh man. I love Sky Screaming Time actually.”
Oh and the milk floats are electric
