He [Hockney's father] hardly ever left Bradford. He was a member of CND and a socialist with a rather romantic and naive idea of what Soviet Russia was like, all cornfields and ballet. He would have gone mad for email because he was always sending letters to world leaders - Eisenhower, Mao, Stalin - telling them what was what. I think he imagined the Politburo would hold up his letter and say, "Hold everything, Kenneth Hockney has written again!"
