Kate Moss, Noel Gallagher and Lulu have been among the 20,000 fans to see Led Zeppelin return to stage for the first time in 19 years.The legendary band entertained for nearly two hours at the O2 Arena in London, opening their set with the classic Good Times Bad Times.The band's three original members, singer Robert Plant, guitarist Jimmy Page, and bassist John Paul Jones, were joined on stage by Jason Bonham, the son of late drummer John Bonham.The concert was in tribute to Ahmet Ertegun, the music mogul who signed the group to his Atlantic Records label in 1968.Millions of fans from around the world rushed to register for the 20,000 tickets which were allocated for the one-off gig by lottery.On the night, fans were required to present photo ID, the card they used to book their tickets and their confirmation code, in the hopes of deterring ticket touts.The gig, which was rescheduled after Page fractured a finger, included hits such as Dazed and Confused, Black Dog and Stairway to Heaven and Kashmir.An encore brought the rockers back to stage to sign out with Whole Lotta Love."Every track was brilliant," said Terence Baker, 47, from Wimbledon, south London. "They still know how to put on a show after all these years.""Jimmy Page was incredible tonight," added Mary Wallace, 39, from Sunderland."If anything, I think his guitar playing has got better over the years."That's probably the one and only time I'll get to see them in the flesh, so tonight is a very special night."© Independent Television News Limited 2007.
