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.

No, I've never thought that I was gay. And that's not something you think. It's something you know.

The kind of vocal exaggeration that I developed was based on what key songs were in.

People run away, pull their hair, go off in different directions, nodding their heads and going, "Oh, God." I am slightly disheveled, I think. I'm really pleased that I am, because otherwise I could be in a really, really dull and boring place now, as a musician, at least.

Possibly the whole creative whirlwind of any musician's life is based on garnering and developing and absorbing more and more experience.

I like to make my voice sound like a piece of tin that's been stuck on the side of a chair, lifted up as far as it would go and then let to spring - "doooiiinng." I like to make it into a piece of metal from time to time and I can do it, both with the movements in my throat and with, uh, my little toys... So I like to take it beyond just a voice, more into the realms of a weapon.

I think I surprise myself.
