The one person who's disappeared out of the business is the A&R man. Because the listener at home becomes the A&R man. He's the one who chooses what tracks he wants on the album. And that's cool.

My first guitar was like a campfire guitar. And it was left at a house that my family had moved into... and the guitar was at the house. It was all strung up. It's normally something that would be beyond a bit of rubbish.

The whole thing about 'The Rover' is the whole swagger of it, the whole guitar attitude swagger. I'm afraid I've got to say it, but it's the sort of thing that is so apparent when you hear 'Rumble' by Link Wray - it's just total attitude, isn't it?

'Communication Breakdown' - it was punchy and direct, with a real attitude that was different to other bands going around.

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.

With Led Zeppelin, it has always been that mystique of how the music is done - how it works, why it works.

Playing in my early bands, working as a studio musician, producing and going to art school was, in retrospect, my apprenticeship. I was learning and creating a solid foundation of ideas, but I wasn't really playing music.

I wanted to emulate music from America - young punks playing rock n' roll is what it was. I read part of Keith Richards' autobiography, and it was totally parallel with me, learning from American records.

Nobody could have predicted the effect of John Bonham's drum introduction on 'Good Times, Bad Times,' because no matter what he'd played in before, he'd never had the chance to flex his muscles and play like John Bonham.

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.
