Since the full schedule was revealed at the end of May, people have been sharing their theories about who the mystery act will be - and there are some options that seem more plausible than others. Glastonbury Festival is famous for staging secret sets on smaller stages like the John Peel Stage and the Park Stage. So to put the Churnups on the main Pyramid Stage seems to indicate that the act is very popular and the festival is expecting a large audience to be interested in watching the show.

Somerset Live has trawled the internet to find the best theories for the identity of the puzzling act. And there are a lot of theories out there. A frenzy of wild speculation has been unleashed among music fans after a band that doesn't exist was revealed on the line-up for the Pyramid Stage at Glastonbury Festival 2023. "The Churnups" will perform on the main stage on Friday June 23, but there is no record of any band with that name, and this has sparked a flood of rumours and conjecture online. Pulp is currently embarking on a UK reunion tour and has a gap in their schedule around the time of Glastonbury, which this year is from June 21 to 25. Many Glastonbury fans remarked that the set was longer than it usually is in that slot at an hour and 15 minutes. The name "The Churnups" also appears to indicate a mix of sorts. This could mean a mix of different artists. But nobody really knowsAnother band that has been heavily rumoured to be The Churnups are Blur. The Britpop legends are famous for '90s hits like Song 2 and Parklife, and they headlined Glastonbury Festival 2009.

Pulp are one of the most heavily mentioned names. They are another Britpop heavyweight, with well-known songs like Common People and Disco 2000, and they performed at Glastonbury in their heyday in 1995 and 1998. Glastonbury Festival has not revealed any details about the mysterious band. However, many people are theorising that The Churnups are a massive act hiding behind a fake name. Whether The Churnups' true identity will be officially revealed ahead of their show is yet to be seen but Emily Eavis suggested it might. Speaking to Radio 2 ahead of the Churnups performance, the festival organiser told presenter Zoe Ball: "It's coming soon". She said: “To be honest, I think there’s a lot of rumours that are circulating about The Churnups one of which is true. I don’t think I can completely confirm but it’s coming soon." The Foos – who have previously played surprise gigs under the moniker The Holy Shits – have space in their schedule to make a return to Glastonbury as it stands. They headlined the event in 2017, after being forced to cancel their appearance two years prior.They aren't strangers to a secret set at Worthy Farm either. They appeared in an unannounced slot on the Park Stage in 2011. Arctic Monkeys, Guns N’ Roses and Elton John will headline this year’s Glastonbury. During a new interview, the latter said the historic appearance was “the most wonderful way to sign off in England” before he retires from touring.

Foo Fighters have previously played under a different name in 2014. They performed a tiny secret gig in front of 600 people as The Holy Sh*ts. In addition, 2023 marks 25 years since Foo Fighters first performed at Glasto – on the same day and in the same slot as The Churnups are billed. The ChurnUps have no digital presence but have been given a top slot on the Pyramid Stage on Friday, June 23. The band is set to play in between Texas and Royal Blood from 6.15pm until 7.30pm.

Blur are another name that has been mentioned. Damon Albarn and his band, who are set to play a headline show at Wembley in two weeks' time, are touring Europe this year. Some have speculated that The Churnups could be a nod to bassist Alex James' love of cheesemaking.

Foo Fighters are playing in North America throughout June and July. However they do have a big gap in their tour schedule between June 18 and July 8, so there's plenty of time to get to Glastonbury Festival. Aside from The Churnups’ set, there are multiple ‘TBA’ slots on the Glastonbury 2023 line-up – the most prominent being two on the Woodsies stage (Friday, June 23 at 7:30pm BST, and Saturday, June 24 at 6pm BST).
