'Rednecks' always made me nervous to play, but I'm glad I wrote it and I continue to play it. It's just that the language is so rough.

I've written a song for Prince. I never showed it to Prince, but just to see if I could do it. At the time, when I sort of knew him, he was recording a song a day. I wondered if I could do that. So I wrote it.

I once had dinner with Madonna and I wasn't nervous but within about a minute I found myself talking about underwear.

What I'm most pleased about is that there's no particular decline. The songs I wrote 40 years ago are no worse and no better - there's a consistency.

I am not overlooking any mail. I'm looking at all of it. I even wrote back to the Viagra people.

I've always had a lot of respect from the people I respected.
