I don't see what the point is in growing up.

I love the feeling of letting fly, of pushing as far as I could go with my voice. The only way you can really graduate how you do it is by doing it regularly to people who don't have to be super impressed. You can do it in the studio all day long but you don't get the flashback that you get onstage.

I have to try and change the landscape, whatever it is.

I'd break out in hives if I had to sing (`Stairway to Heaven') in every show. I wrote those lyrics and found that song to be of some importance and consequence in 1971, but 17 years later, I don't know. It's just not for me. I sang it at the Atlantic Records show because I'm an old softie and it was my way of saying thank you to Atlantic because I've been with them for 20 years. But no more of `Stairway to Heaven' for me.

I think I could sing and shear a few sheep at the same time.

Austin - it's a stimulating center. In this conversation, the very first two questions were talking about my kind of wanderlust and my adventures. Some people at my time in life travel forever. I don't know whether it's the British or the Australians - whoever it is, you can kind of stagger into some sort of far-off bastion in the middle of nowhere, and you'll find someone from Britain or someone from Australia or maybe an American.

I really had to think and learn about musical intervals.
