In a churnup for the books: yep, it was Foo Fighters. In the biggest nudge-wink, David Brent "Ooh, no, see ya later" play of Dave Grohl's life, a mysterious band called The Churnups were added to Glastonbury's line-up the other week. Some people reckoned it was Pulp, everyone else just knew who it actually was.
The secret wasn't much helped by dropping loads of hints, and then photos of Dave Grohl onsite at Worthy Farm appearing all over twitter today as the fest got going. But we're very glad it happened.
Opening with All My Life, they played a riotous set that took in classic bangers Learn To Fly and a scorching The Pretender, as well as bringing out Dave's daughter Violet for Show Me How from their emotional new album, But Here We Are. And who was that in the wings? None other than Beatle and Foo friend Sir Paul McCartney.
Dedicating a climactic Everlong to Taylor Hawkins (whose bird logo graced new drummer Josh Freese's drums, today decked out with a black metal Churnups logo for his first UK show since getting the permanent job), Dave thanked the audience for "sticking with us for 28 years, and showing us how to start over."
Even better, he promised to come back "next summer, for a whole fucking tour".
So, yeah, it was them. It was great. Now get ready for proper Foos shows in 2024.
