More than 90,000 people showed up for a free Love Music Hate Racism gig at London's Victoria Park.
Hard-Fi's Richard Archer flew in from the US for the gig in east London
The festival was headlined by The Good, The Bad and The Queen and also featured sets by Hard-Fi and The View.
The weather could have been better for the crowds, although some sunshine eventually broke through the rainclouds as Damon Albarn's band took to the stage.
There were a number of political speakers including British director Gurinder Chadha, who also attended the original Rock Against Racism gig in 1978.
Also hanging around backstage area were Fyfe Dangerfield from Guillemots, Carl Barat of Dirty Pretty Things and Ed Larrikin.
Hard-Fi took to the stage midway through the afternoon. Frontman Richard Archer flew back from the US especially to play the gig, arriving on a 10-hour flight from Houston just hours before the event.
Bandmate Steve Kemp told Newsbeat, it was a worthwhile event: "There are so many young people out there. Even if you get though to just one person, it was worth the time."
The View singer Kyle Falconer revealed the band are heading into studios in Wales and Spain in the next two months to start recording their new album.
They used the opportunity to unveil some new material, including the songs Shock, Horror and Glass Smashed.
Falconer said he had enjoyed playing the show:
"It was good, couple of mince ups on the guitar but it was good."
Former Sham 69 singer Jimmy Pursey performs White Riot by The Clash
Babyshambles bassist Drew McConnell played with his Helsinki side project and invited various special guests on stage including Mercury nominee Fionn Regan, The View and former Sham 69 singer Jimmy Pursey.
The punk frontman recreated his performance of The Clash's White Riot, which he performed at the Rock Against Racism four decades ago.
McConnell also played with Reverend And The Makers' Jon McClure, who revealed they are working in the studio with former Arctic Monkey Andy Nicholson and a British-Iraqi rapper called Lowkey.
It was a big day for The Clash's Paul Simonon to return to the same venue, 30 years on, with his new band The Good, The Bad, and The Queen as headliners once again.
Organisers confirmed Morrissey had donated £75,000 to the event after a sponsorship deal fell through.
None of the artists, which included Roll Deep, Bashy and Jay Sean, were paid to perform.
