You get a chance like that maybe once in your lifetime, and you are lucky to sustain it over that period of time. It doesn't mean to say that whatever I do in the future has no substance to it - I may present some new material I've got, and there are definitely new angles of doing it - but I'm not looking to recreate another Led Zeppelin.
There's such a currency to Led Zeppelin, or the members of Led Zeppelin. If I put it to you this way, on the run-up to the O2 concert, the only music that we played was music of Led Zeppelin - the past catalog stuff; that's what we played on the way towards shaping up the set list for that. But we played really, really well.
From meeting Robert Plant, John Bonham, and John Paul Jones, teaming up, rehearsing, playing selected gigs outside of Britain, coming back into Olympic Studios to record the first album, and then going to America, which we crack open like a nut with the debut record - all that happened, literally, within months.
