The Rolling Stones - Eric Clapton And Florence Welch Join The Rolling Stones Gig

A video featuring Johnny Depp, The Who guitarist Pete Townshend and Iggy Pop talking about the rockers kicked off the show at the O2 Arena.

The Lust For Life singer joked of the band, "We'd never seen people with teeth like that. And skin like that. Ugh!...The sound of Keith's guitar - it was like being hit with a dead mackerel."

Frontman Mick Jagger referenced the fact that their set over ran during their first London gig on Sunday (25Nov12), costing them $160,000 (£100,000) in fines for breaking local council rules about acts adhering to a strict curfew.

He also took the opportunity to joke about the astronomical ticket prices some fans had paid to attend the concert, telling the crowd, "We're more relaxed tonight, we'll get to play the whole thing. We had to pay £100,000 because we went on too long. That's like... 10 seats!"

Florence + The MAChine frontwoman Welch joined Jagger for Gimme Shelter and guitar legend Eric Clapton also took to the stage, playing blues guitar on the song Champagne and Reefer.
