The existing members of Led Zeppelin reunited in London on Friday (21Sep12) to promote a new concert movie about their 2007 get together for late music mogul Ahmet Ertegun.

The O2 Arena gig marked the last time Jimmy Page, Robert Plant and John Paul Jones played together and sparked months of rumours suggesting the trio would tour - but the dates never materialised.

The press conference held to launch the film, The Celebration, was more than a little chilly at times as media members quizzed the group about another reunion and possible tour.

Guitarist Page simply responded to one journalist, "Let me ask you a question - have you seen the film? Did you enjoy it? Then we've done our job, haven't we?"

Speaking about the film, Plant confessed that his performance on some tracks was edited because, "I was running out of steam".

And the three former bandmates had nothing but praise for drummer Jason Bonham, who filled in for his father John at the London show in 2007.

Page stated, "Nobody else could have done it."
