Onstage it was always comfortable for me because that's where I felt at home. Offstage it was a different situation. I was still shy offstage and unfortunately, my shyness and my inability to communicate and really have great conversations or be part of the gang - in inverted commas - led me to the drug addiction, which, you know, blighted my life for 16 years because I thought by doing that it would make me join in.

I've been coming to America since 1970, and it's like my second home, but I've never felt such a divided country, ever. I didn't think it would get to this point, and it breaks my heart.

And these [pharmaceutical] companies are still threatening to sue. And it's like, you know, do you not have a conscience? Do you not want the world to be a better place? You're still making a profit. How much more of a profit do you want to make?

I don't want to be married. I'm very happy with a civil partnership. If gay people want to get married, or get together, they should have a civil partnership. The word 'marriage,' I think, puts a lot of people off. You get the same equal rights that we do when we have a civil partnership. Heterosexual people get married. We can have civil partnerships.

It took a child. It took a child with a blood transfusion not only to wake me up, but to wake America up, basically. I mean, I read about his plight in a doctor's office in New York in a magazine. I was so outraged about it that I contacted the family. We became friends. I helped them move to another place in Indiana. And we became constant friends.

I had no balance in my life. I was this one person onstage and this person offstage, who really didn't know much about living.

In my 20s I was so ignorant about drugs, and so naive. I mean, my band was smoking marijuana for years; I didn't even know what a joint was. And I'd never seen a line of cocaine in my life. And I don't know whether it was bravado or - OK, I'll join in. But my stupidity, I had a line of coke, and that started the whole process.
