I've always been dead set against festivals, really suspicious and wary.

You know, no one should be marginalized in society when it comes to health. And, you know, we have - as a foundation, we have tried to champion those people [sex workers, needle users, intravenous drug users, prostitutes] and be by - be by their side and say, listen, these people cannot be forgotten. If you forget about them, then the disease is never going to go away.

You can call me a fat, balding, talentless old queen who can't sing, but you can't tell lies about me.

Until I can visualise what the lyrics are about and see the story or whatever, I can't hear the melody.

From the start, I've always admired Eminem's thinking. That's the reason I wanted to appear on the Grammys with him when I was asked. Eminem has the balls to say what he feels and to make offensive things funny. That's very necessary today in America, with people being muzzled and irony becoming a lost art. Artists like Eminem who use their free speech to get a point across are vitally important. There just aren't many people in the world with balls that big and talent that awesome.

When I say I don't have to write pop songs anymore, there's no way I'm going to get on the radio at 60 years of age unless I'm doing a duet with [Lady] Gaga or I was on All of the Lights, which was a Kanye West record that managed to get on the radio.

I don't want to spend the rest of my life talking about when I used to drink or when I used to take drugs. I'm more interested in the future.
