You get as much out of rock & roll artistically as you put into it. There's nobody who can teach you. You're on your own and that's what I find so fascinating about it.

The blues appealed to me, but so did rock. The early rockabilly guitarists like Cliff Gallup and Scotty Moore were just as important to me as the blues guitarists.

There will be a Led Zeppelin as long as there's a Jimmy Page, John Bonham, John Paul Jones and Robert Plant. This isn't a nostalgia band playing the hits forever. If anything ever happened and somebody left - which I really can't see happening - I don't think we'd bother to carry on. The magic for me is as it is now.

You know what you can gain when you sit down with the Moroccans. As a person and as a musician. That's how you grow.

I don't care what critics and other people think.

The only term I won't accept is "genius."

I think it's time to travel, start gathering some real right-in-there experiences with street musicians around the world.
