I like to comprehend more or less everything around me - apart from the creation of my music. It's an obsessive character trait that's getting worse. I don't switch the light on and off 15 times before I leave the room yet, but something's going wrong.

You would find in a lot of Zep stuff that the riff was the juggernaut that careered through and I worked the lyrics around this.

I'm not a flowerchild or anything like that... whatever it was.

I really had to think and learn about musical intervals.

I'm not saving lives. I'm singing and I should go placidly and joyously through the whole thing and work hard and not take it for granted. It's great to have this gift.

It's not some great work of beauty and love to be a rock-and-roll singer.

Led Zeppelin was a very sensitive and beautiful animal beast.
