The AIDS disease is caused by a virus, but the AIDS epidemic is not. The AIDS epidemic is fueled by stigma, by hate, by misinformation, by ignorance, by indifference. Science has accomplished miracles over the past 20 years, and science can now end this disease - but it cannot end the epidemic. We need more than medicine. We can do something about these things. We need to speak out about the changes we need to make in our society.

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.

If I was to say what I am, I'd be a Labour man. I like Tony Blair a lot, I think he's a good man. And in America I'd definitely be a Democrat; I'd never be a Republican.

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

But until we get rid of that shame, then people are going to stay underground, they are not going to get tested, and we're facing an uphill battle [with AIDS].

And we have come so far like that. I mean, the advances on the medication side have been enormous, and the advances on the human side have been enormous. But we still have this stigma to get rid of, and then we really will be able to see the light at the end of the tunnel.

Sometimes you can't see the wood for the trees as an artist.
