Seventies Britcom centred on workers of the Luxton & District Traction Company. The main characters are Stan Butler, a bus driver, and his best mate and conductor, Jack Harper. Their arch-nemesis is pen-pushing bureaucrat bus inspector Cyril "Blakey" Blake. Recurring characters include Stan's mum, sister Olive and brother-in-law Arthur. Olive and Arthur are unhappily married, which is often joked about. Seventy-four episodes were made from 1969 to 1973. Three spinoff films were also made. Came fifty-third in Britains Best Sitcom.
