Stan Stennett had previously starred in Crossroads in 1970 playing, Harry Silver, who held Mr Booth (David Lawton) and Tish Hope (Joy Andrews) at gunpoint.
The role of Harry Silver had been very brief, but Stan Stennett remembered it and suggested that Harry might return in 1981 - and shoot Meg Mortimer (Noele Gordon), who was being written out.
Crossroads producer Jack Barton thought this might make Stan the most unpopular man in the UK, but instead suggested a brand new and very different role - Sid Hooper.
Sid, was revealed as being the wandering husband of boarding house keeper Mavis Hooper (Charmian Eyre), and moved in with her. His weakness for gambling and women soon showed, and he departed from King's Oak after his new boss at the garage, Reg Lamont (Reginald Marsh) bought him off - giving him money to pay off his gambling debts on condition that he gave up his job at the garage, leaving the way open for Mac to take over.
Sid was absent from the village from some time, finally returning when Mavis was taken ill.
Re-employed by the garage, Sid became a much nicer guy - and he ramained in Crossroads until 1987.
