Radiohead stars Jonny Greenwood and Thom Yorke served up the first big surprise at this year's (10) Glastonbury festival when they hit the stage for an unannounced set.
The bandmates were introduced by festival organiser Michael Eavis, who built up the moment by calling it "the biggest surprise of the weekend."
A grinning Yorke then stepped forward and announced, "Hi, my name is Thomas Yorke," before playing his The Eraser hit solo on the piano.
He went on to perform Harrowdown Hill and Black Swan before Greenwood joined him onstage for a rendition of Cymbal Rush, Wishes Fishes/Arpeggi and Pyramid Song.
They closed their short set with Radiohead fan favourites Karma Police and Street Spirit (Fade Out) and then Yorke told fans to "have a brilliant festival" as he shuffled offstage.
