I once went to a demonstration in Aachen against fare increases on public transport. A police officer pulled out a bunch of my hair, and there were a lot of violent beatings. That's when I thought to myself: You'd better leave it alone.

Sometimes I smoked opium. And I also took LSD - for a while, quite a lot of LSD, in fact. But I never had any bad experiences. I stopped in 1985. I'd had enough, and I don't miss it, either.

One is a criminal to some people and an artist to others. I can understand that. In a legal sense, I am a convicted criminal.

Did I want to spend all my time working on a painting? No, I wanted to have fun, travel, meet women and live life.

I went to the flea market in the morning and charged tourists money to take pictures of me. I looked pretty wild, with hair down to my waist, Indian robes, a floor-length fur coat. There must be lots of photos of me out there.

You can't paint pictures of love. You can only imagine them. So I suppose I don't need a painting by another artist. I have enough of my own.
