Bruce Springsteen might have been the headliner but if it was mass singalongs you were after, Kasabian and Dizzee Rascal owned Glastonbury on Saturday.
"I've been on that stage before with Arctic Monkeys," Dizzee said after his late afternoon set.
"But it's nice to do it for myself, my own set and carry it through for an hour. I couldn't have asked for it to go any better. When you dream of being a pop star or a rock star... this is it."
Dizzee Rascal appeared on stage in a suit despite the baking hot sunshine - dressed as the Prime Minister - a nod to his recent appearance on Newsnight which played out on big screens.
Kicking things off with a quick rendition of The Ting Tings' That's Not My Name, which he originally did for Radio 1's Live Lounge, he quickly moved on to Jus' a Rascal.
Maximo Park's Paul Smith was spotted watching and loving it with his girlfriend - as were the other 80,000 crammed around the stage.
There was plenty of audience participation from the off, with everyone shouting out the words to Sirens and Dance Wiv Me. He even managed to fit in a Michael Jackson medley.
"Just played a couple of tunes, as tributes. It didn't feel right to be up there and not do something," he said.
"I was shocked when I heard the news. I'd been playing Street Fighter in my house with a couple of mates, and I was just glued to the TV for hours.
"It's one of those moments, people will say 'Where were you when Michael Jackson died?' Nuts."
Lots of love too for the new tracks Dizzee played out from his next album - out in September - including next single Holiday.
That features his mate Chrome who joined Dizzee on stage, and was produced by Calvin Harris who Dizzee bigged up on stage.
And of course the big encore of Bonkers - which one fan shouted afterwards was "one of those real Glastonbury moments!"
Lily Allen grabbed a lot of attention in her blonde wig
Elsewhere Little Boots covered MJ's Earth Song in the Guardian Lounge, and Klaxons came on in fancy dress for their 'secret' set over in The Park.
Playing out some new tracks, Simon dressed as Beetlejuice, James was Edward Scissorhands and Jamie had a headless suit on.
Meanwhile, sinking ciders in the backstage bar was a very smiley Nicola from Girls Aloud, Skins star Kaya Scodelario (who plays Effie) with an entourage, and Reese from Hollyoaks.
The photographers chased Lily Allen around - she'd teamed her wellies with a sparkly dress and blonde wig.
Damon Albarn was fitting in a lot of chillaxing ahead of Blur's Sunday night headline set. He got a spot at the side of the stage to watch Spinal Tap - he loves them apparently - before chatting to Zane Lowe in the sunshine.
Ahead of Kasabian's anthem packed set - just before headliner Bruce Springsteen on the Pyramid Stage - the band were spotting stars too.
Serge said he was too nervous to actually say hello to anyone, including The Boss himself, who it's rumoured specially requested them on the line up.
"We heard the same rumour!" he said. "I just saw him in the corridor and there was not a lot of love there! I didn't even say hello though. He gave a kind of smile - maybe."
Bruce meanwhile was jumping on stage with Gaslight Anthem for a track in the John Peel tent, before catching Passion Pit's packed out set there too.
But Kasabian were also very excited about their other celeb spot of the day:
"Status Quo are at our hotel! That is amazing," Serge laughed. "What a pair of absolute lords they are.
"They were just having a cup of tea downstairs," Chris added. "It's insane. We didn't say hi though. Tom weren't there, we needed Tom."
"When it's like this there's nowhere better in the world," said Serge.
"I'm kind of sad to leave, but my organs won't be though. The two day affair really does start to take its toll. 24 hours is easy to get over!"
