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.

I'm not a guitar hero.

I always want to do my very best, and it's frustrating to have something hold me back.

We were lucky in the days of Led Zeppelin. Each album was different. We didn't have to continue a formula or produce a certain number of singles. Because, in those days, radio was still playing albums. That was really good.

Led Zeppelin wasn't a corporate entity.

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.

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.

In the wake of the San Francisco scene, ears were alive. It was a listening generation.

Here's where it goes with Led Zeppelin. It didn't matter what was going on around us, because the character of Led Zeppelin's music was so strong.

Having the facility to have this multitrack at home, I could try experiments with sort of all of the instruments, giving them different treatments so they didn't actually sound, necessarily, like the instrument itself.
