Led Zeppelin didn't get that kind of Beatles screaming. We had a more sort of macho crowd. But I remember once in the early days of The Yardbirds, we were playing on an ice rink, and the stage was mobbed by screaming girls. I had my clothes torn off me. That's a really uncomfortable experience, let me tell you.

You can't buy time. Everything, for me, seems to be a race against time. Especially musically.

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.

Sometimes, I must admit, I'd like to have a second guitarist onstage with me, but it wouldn't look right. I'd like to play for another 20 years, but I don't know... I just can't see it happening. I don't know why. It's a certain foreboding... a funny feeling... vultures.

I like change and I like contrast.

We were never a band that did 96 takes of the same thing. I had heard of groups that were into that kind of excess around that time. They'd work on the same track for three or four days and then work on it some more, but that's clearly not the way to record an album. If the track isn't happening and it creates some sort of psychological barrier, even after an hour or two, then you should stop and do something else. Go out: go to the pub, or a restaurant or something. Or play another song.

I really wasn't needed... Just straightening up riffs, that's all. Just two guitarists doing it instead of one.
