Since he burst onto the art scene in the mid-Sixties, David Hockney has become one of the most popular and successful British painters of the twentieth century. His reputation has been made both by the appeal of his work and his passion for and skill in talking about painting. To mark his fiftieth birthday in 1988, London’s Tate Gallery staged a major retrospective of his work. Melvyn Bragg joins Hockney for an exclusive private view of the exhibition and they are seen discussing pieces from all stages of Hockney’s remarkable career.
