As Andrew Lloyd Webber prepares to open his new musical about Profumo and Stephen Ward, Matthew Sweet explores 1963 - the year that 'sexual intercourse began' according to Philip Larkin's poem. Joining Matthew are Lord Hutchinson who defended Christine Keeler; journalist and campaigner Bea Campbell; actress and singer Lynda Baron; Don Black, lyricist for the musical Stephen Ward; Richard Davenport-Hines, author of An English Affair; and Geoffrey Robertson QC, leader of a campaign to clear Stephen Ward's name.
