From the classical guitar right through to the furthest electrical experiments and everything in-between, it's amazing what the guitar can actually do. I mean, when one thinks about sounds.

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.

Just because you play bass, doesn't mean you have no presence.

Seeing people's faces, really getting off on them, makes me incredibly happy. Genuinely.

Many people think of me as just a riff guitarist, but I think of myself in broader terms. As a musician I think my greatest achievement has been to create unexpected melodies and harmonies within a rock and roll framework. And as a producer I would like to be remembered as someone who was able to sustain a band of unquestionable individual talent, and push it to the forefront during its working career. I think I really captured the best of our output, growth, change and maturity on tape - the multifaceted gem that is Led Zeppelin.

I'm not a guitarist as far as a technician goes, I just pick it up and play it. Technique doesn't come into it.

I'm pretty optimistic about the future of rock... it will be back to composition as in classical music or jazz.
