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 don't want to scream 'Immigrant Song' every night for the rest of my life, and I'm not sure I could.

It's sort of a feeling of power onstage. It's really the ability to make people smile, or just to turn them one way or another for that duration of time, and for it to have some effect later on. I don't really think it's power... it's the goodness.

All over the world, the idea of creating an melange of international musics, it's a very healthy thing.

There are always generic terms like 'Americana', but there are no boundaries as to where it can go.

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.

It's a two-dimensional gig being a singer, and you can get lost in your own tedium and repetition.

I think I'm prone to panic.

You feel quite distant by playing at huge stadiums year after year, where you only can see a great darkness in front of you.

So for a long time I closed my eyes to the possibility of America having a white voice.

I've still got a twinkle in me.

I wanted my voice to be a tenor sax, really.

Theatres are built because they were the boards for entertainment.

I know that bands that haven't put out a record for 10 years are playing to 20,000 people a night. But that's not the achievement.

There's nothing worse than a bunch of jaded old farts, and that's a fact.

I can find my way from 500 A.D. through to 1066 pretty well as an amateur historian.

I hate wasting time.
