The gut-strung guitar, the classical guitar, that is a whole different world on its own. When you think what the guitar can do and what every individual player does with a guitar, everyone has their own identity coming through the guitar.

I don't go walking into things blind.

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.

If I ever really felt depressed, I would just start putting on all my old records that I played as a kid, because the whole thing that really lifted me then still lifted me during those other times. It was good medicine for me, and it still does that for me when I put something on. Isn't it wonderful that we've got all that good medicine? I think it's got to be all part of our DNA, this mass communication through music. That's what it is. It's got to be, hasn't it? Music is the one thing that has been consistently there for me. It hasn't let me down.

I have a voracious appetite for all things, worldly and unworldly.

You can't just find yourself doing something and not happy doing it.

Once I got a guitar that was relatively user-friendly, but not super-duper easy, I really came on as a guitarist, at that point. It helped. It was a super-expensive guitar either, but something needs to steer you a bit, if you're playing an instrument that is really hard.
