Like many successful British sitcoms, this show was remade into an American version called Open All Night (1981), in 1981, starring George Dzundza, as the owner of a 24 hour convenience store with chat show host, David Letterman making a cameo appearance in at least one episode. The series was canceled after just one season of 13 episodes.
