Last of the Summer Wine [SEP] Introduction
Due to the age of the main cast, a new trio was formed during the 30th series featuring somewhat younger actors, and this format was used for the final two instalments of the show. This group consisted of Russ Abbot as a former milkman who fancied himself a secret agent, Luther "Hobbo" Hobdyke, Burt Kwouk as the electrical repairman, "Electrical" Entwistle, and Murphy as Alvin Smedley. Sallis and Thornton, both past members of the trio, continued in supporting roles alongside the new actors.
