Since I was a kid, I've had an absolute obsession with particular kinds of American music. Mississippi Delta blues of the Thirties, Chicago blues of the Fifties, West Coast music of the mid-Sixties - but I'd never really touched on dark Americana.
I'm just lucky because my kids are grown-up - I love them, very proud of them, and we are in close contact as big-time friends, but they don't need me that much now and I can actually enjoy this wonderful world of music.
There have been people I've warmed to over the years but, as the situation I'm in is so fleeting and transient, I've always known it's going to be over kind of real quick.
You can't give up something you really believe in for financial reasons. If you die by the roadside - so be it. But at least you know you've tried. Ten minutes in the music scene was the equal of one hundred years outside of it.
The trouble is now, with rock'n'roll and stuff, it gets so big that it loses what once upon a time was a magnificent thing, where it was special and quite elusive and occasionally a little sinister and it had its own world nobody could get in.
I realized what Led Zeppelin was about around the end of our first U.S. tour. We started off not even on the bill in Denver, and by the time we got to New York we were second to Iron Butterfly, and they didn't want to go on!
People have got to let their bodies breathe a little bit more. That's the great thing about being a pompous, jumped-up rock god. There's plenty of air around you.
