I believe in fairies. Although I can't prove they exist, nobody has ever managed to prove to me that they don't. - Peter Blake

I don't think artists should be sponsored. You should not rely on grants. You either make a success of your art or you don’t. I worked as an artist for a number of years without making much money – I have never had any financial backing in that way. Things are now very good for me but for a lot of the time things were not.

Brian Sewell is a fool. For some years he seemed to have it in for me and Hockney and [R.B.] Kitaj. Even if he wasn't writing about us he'd always find a way of bringing us in. He'd say, "so and so was a bad artist but not as bad as Hockney, Kitaj or Blake." Things like that.

My dealer was a friend of the Beatles and the Stones, and he suggested they used a fine artist. I talked to the Beatles at length about what the cover would be. I worked out it would show the moment after they had played in a bandstand in the park. My big contribution was the life-size cutouts, the magic crowds."
