I can communicate far better on a guitar than I can through my mouth.

There's such a wealth of arts and styles within the guitar... flamenco, jazz, rock, blues... you name it, it's there. In the early days my dream was to fuse all those styles. Now composing has become just as important.

I'm trying to photosynthesize like a plant. I'm off eating. Although I am making a lot of banana daiquiries in my room in the blender I've got, with lots of powdered vitamins in them. This tour I'm going to get some Afghani hangings and put them in my room, so that my hotel rooms look like mosques.

I can tell how far I ought to be going, I know how to get there, all I've got to do is keep playing.

We kept moving forward and didn't try to recreate the past .. the approach to each album was radically different every time. Many bands would have some success and, because they were locked into having a single - something we didn't have to worry about - they had to make sure there was something similar on the next album ... that was never the idea with Led Zeppelin .. the goal was to keep that spark of spontaneity at all times.

Almost the moment he died, they put him in Playboy as one of the greatest drummers, which he was - there's no doubt about it. There's never been anybody since. He's one of the greatest drummers that ever lived.

That's the music that I play at home all the time, Joni Mitchell. Court and Spark I love because I'd always hoped that she'd work with a band. But the main thing with Joni is that she's able to look at something that's happened to her, draw back and crystallize the whole situation, then write about it. She brings tears to my eyes, what more can I say? It's bloody eerie. I can relate so much to what she says. "Now old friends are acting strange/They shake their heads/They say I've changed."
