Richard Michael Hills (17 January 1926 – 6 June 1996) and Sidney Green (24 January 1928 – 15 March 1999), informally known as Sid Green and Dick Hills, were a British partnership of television comedy writers, at their highest profile during the 1960s. During the early eighties they wrote for the British double act Cannon and Ball, occasionally recycling material that had been used for Morecambe and Wise in the sixties.
