I have a voracious appetite for all things, worldly and unworldly.

I'm not interested in turning anybody on to anybody that I'm turned on to... if people want to find things, they find them themselves.

I don't care what critics and other people think.

But if you want me to knock Kingdom Come, all I will say is that I heard the guitarist said he'd never heard my playing, and I'd defy any guitarist in American not to have heard Led Zeppelin.

You absorb so much from whatever your environment is, as an artist, and you learn to take from it what can help you create.

Right from the first time we went to America in 1968, Led Zeppelin was a word-of-mouth thing. You can't really compare it to how it is today.

The beauty of the band was you never knew what was going to come out next.
