The 1975 and Metronomy delighted Glastonbury-goers by performing a secret show in the William Green's tent last night (Thursday 26 June).
The main event really kicks off today, with a less-than-secret opening set from Kaiser Chiefs on the Other Stage at 11am - before the day sees performances from the likes of Arcade Fire, Elbow, Lily Allen, Interpol, Paolo Nutini and many more.
But, that didn't stop the action coming into full force last night, when rumour spread across the Worthy Farm site of a surprise appearance from The 1975 and Metronomy (there were also whispers of Coldplay and The Libertines, but they ultimately came to nothing).
The Williams Green Stage was already full for some kind of bafflingly poor musical bingo act, playing huge tracks by the likes of Blur, Arctic Monkeys and the Grease soundtrack as attention-starved Butlins rejects pranced the stage like drunk uncles at a wedding and urged early drunkards to 'put their hands up', 'make some noise'.
Then, crowds grew beyond the tent and into the main pathway as The 1975 took to the stage - with frontman Matt Healy clearly in high spirits and seeming oddly sober as they led the band through a frantic hit-packed set, squealing "GLASTONBUUURRRYYY" repeatedly.
At one point, the band very briefly halted their set for Healy to protest a can being thrown at him and mild upset in the crowd, before the band completed their with rapturously received renditions of 'Chocolate' and 'Sex'.
The crowds largely remained in place from a delightfully summer-y set from Metronomy, again proving that the sheer class and calibre of their back catalogue will see them headlining major festivals in the years to come.
