In the crowd, a dozen or so revellers dressed as lobsters push their way to the front. A chant breaks out – “Pinchy pinchy kiss kiss! Pinchy pinchy kiss kiss!” – and the audience all point their lobster fingers in the air. Then, as anticipation reaches fever pitch, a beaming man wearing a lobster T-shirt arrives onstage and launches into a series of sunny Euro disco songs tackling the day’s hot topics: things like how nice the London Eye is and why his local cafe is great.

This is undoubtedly one of the daftest performances Glastonbury has ever staged. “Let me see your claws,” Lekiddo tells his cult devotees at one point, before handing out santa hats and launching into, of all things, a Christmas song. But it’s also unrelentingly joyous – all major chords and cheesy sugar-rush hooks. Lekiddo’s songs – performed over a backing tape and with what appears to be a broken overhead projector beaming images onto the backdrop – don’t fit into any conventional pop categories. There’s a nod to 80s disco here, the odd bit of tropicalia thrown in, and some bizarre/terrible lyrics. But, ultimately, this is outsider music that is all the better for not having a clue how to fit in.

The party tunes are are matched by a party atmosphere. When the gig’s over, Lekiddo has to be virtually dragged from the stage as he starts singing To the Beach again, this time a capella. When he finally leaves, the audience mob him for selfies and the fancy dress lobsters start up the chant again: “Pinchy pinchy kiss kiss!”

It’s only Thursday night and it feels like Glastonbury 2015 has already peaked. Florence, Kanye, Daltrey … the bar has been set.
