Fatboy Slim (pictured at a previous Creamfields) topped the bill
Fatboy Slim, The Gossip, Ian Brown and Pendulum were among the headline acts who rounded off the first day at a wet Creamfields festival.
The Gossip, headed by singer Beth Ditto, played a brand new song to rain-lashed fans at the Cheshire site.
The band performed mid-way through the evening on the main stage to a few thousand hardy festival-goers who braved the rain rather than seek shelter in the half dozen other covered stages.
Dressed in an all-in-one black, strappy bodysuit and with newly red hair, singer Beth Ditto told the crowd the song had been written just days earlier.
Speaking to Newsbeat after the set, she said: "It was a trial, I'm really excited about it because we went to this gay party in Paris and it was really amazing and all these gay men were singing the words and they didn't even know it.
"I have a good feeling about it, we call it Crocodile House."
Beth Ditto snapped her mic lead after jumping into fans
The track is so new, it doesn't actually have words yet and is basically an instrumental number with Ditto singing improvised lyrics over the top.
Ditto said: "At the moment, its just me shouting gibberish."
During their chaotic hour long set, Ditto left the stage and jumped headlong into the fans, managing to snap her mic lead.
She added: "I saw people I know, that's the funny thing, I was like 'Hey, this happens to me a lot.'"
Day one highlights
Fatboy Slim also unveiled some new material during his headlining set on the main stage, including a brand new track he worked on with punk legend Iggy Pop called He's Frank
Ian Brown reportedly had a guestlist of 65 people
Unfortunately, The Stooges frontman didn't make it to the festival but was seen on a massive screen behind the DJ.
Fatboy, aka Norman Cook, said: "We recorded him lip synching but he is there in spirit. I am going to see him this week though."
The new tracks were taken from Cook's forthcoming album under the name The Brighton Port Authority.
Cook said: "It isn't actually a new album, it's been going on for years. It's kind of like the lost album, like The Beach Boys' Smile. It's like the lost tapes."
Other highlight performances on the first day of the 10th anniversary of Creamfields included a packed out Chibuku tent for Ian Brown.
The former Stone Roses frontman apparently had a guestlist of 65 people for the festival.
Kasabian will be the first rock headliners on Sunday night
Pendulum once again delivered a show stealing performance on the main stage and Australian newcomers PNAU made an impact in the Annie Mac Presents Arena, performing as the crowd bounced huge balloons around the tent.
On Sunday, there will be sets from the likes of Hercules and Love Affair, Soulwax and Late Of The Pier, with back-to-backs from Paul Oakenfold and Tiesto in the Cream Arena.
Headlining the main stage is Kasabian, who become the first rock band to top the bill, and are expected to play some new material from their forthcoming third album alongside hits like Processed Beats, Empire and LSF.
