I always believed that my work should be unfinished in the sense that I encourage people to add their creativity to it, either conceptually or physically. Back in the 1960s, I was calling for 'Unfinished Music,' number one, and number two, with my artwork - I was taking unfinished work into the gallery. And that's how I was looking at it.

When you go on a stage, before you go on a stage you're really scared and you're really frightened. You don't know what to do. "Why did I say yes to this?" But once you're on the stage you think, "Okay."

My father was a banker, but he was an independent spirit. He was a very good pianist and very much into music.

It's always good to do something that is not a repeat. I just don't believe in repeating.

I don't really believe in going with somebody to have tea and chat. I don't do that. It's just a waste of time.

Performance art is going to be the future. Plays on Broadway are so restricted. But performance art is like haikus, just one line thing. And it's more casual but more interesting.

What is beauty? It's what you love.
