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

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."

Sgt Pepper made me more famous but it did not change me as an artist.

Art in Britain is in a very healthy state. The artists of my generation and older are at their best — people like Howard Hodgkin and Frank Auerbach. The YBAs are still very strong, and it's exciting to wonder what the next generation will bring.
