The London Nobody Knows, 1967 documentary with James Mason
Over a brisk 53 minutes Mason visits Camden's derelict Bedford Theatre music hall, where the artist Walter Sickert once listened to Dr Crippen's wife sing. In the Holborn gents - a proud example of Victorian design - Mason recounts the story of an attendant who kept goldfish in the cistern. "Here you find the only true democracy," notes Mason with the sniffy air of a man unlikely to be caught short after a night on the sauce. "All men are equal in the eyes of a lavatory attendant."
