The Arctic Monkeys thrilled Glastonbury festival-goers when they took to the Pyramid Stage as the Friday night headliners.
The Sheffield rockers delighted the crowds with songs including Crying Lightning, as well as tracks from their new album, like She's Thunderstorms.
There was no surprise that I Bet You Look Good on the Dancefloor proved the biggest hit of the night, with dancing duly carried out by the tens of thousands who crammed into the field to see the set.
Kathleen Pavey, 17, from Bristol, said: "They've been really good at getting the crowd going - but we would have preferred to hear more of the older songs."
Rapper Dizzee Rascal had preceded the band, performing such crowd pleasers as Bonkers. On the Other Stage, trip hop act Portishead headlined, the voice of Beth Orton providing a more relaxed and refined atmosphere than that at the frenetic Pyramid Stage.
Revellers staying up until the early hours were also being given the chance to see Radiohead singer Thom Yorke's Atoms For Peace performing a secret set that did not appear on the official line up.
On Saturday night, all eyes will be on The Rolling Stones make their Glastonbury debut. The veteran rockers are set to perform an explosive 2hr 15m set on the Pyramid Stage, complete with pyrotechnics and a mechanical phoenix presiding over the field.
While fans who paid £205 to attend the three-day event will see the whole show, those watching at home will see just the first hour of the gig. A deal was thrashed out with the BBC, who are providing coverage of the event, after initial fears that only a few songs would be televised.
Festival goers have been stocking up on masks of Sir Mick Jagger and Keith Richards' faces, as well as Rolling Stones t-shirts ahead of the show. Hits including Sympathy For The Devil and Satisfaction have also been cropping up in DJ sets and blasting out from bars around the site in the past few days.
Celebrity fans including Kate Moss are expected to be at the front of the crowds to see the band.
