The Live Earth concert in London, England was held at Wembley Stadium on 7 July 2007.
Chris Rock's explicit language during the introduction of the Red Hot Chili Peppers caused problems with Canadian TV networks and the BBC.
Rock also used the word "nigger" while being interviewed on BBC One by Jonathan Ross, alongside Ricky Gervais.
BBC presenter Jonathan Ross was required to apologize on air for the expletives used by Collins and Johnny Borrell of Razorlight and vowed to give them a "talking to".
The offensive language used by performers at the event and broadcast live before the watershed caused the BBC to be censured by media regulator Ofcom.
