Keep It Up, Jack

Keep It Up, Jack is a 1974 British sex comedy film directed by Derek Ford and produced by Michael L. Green. Jack James (Mark Jones), an unsuccessful music hall entertainer and drag artist, inherits a brothel from his late aunt, and impersonates her in order to seduce the female clients. The film also exists in a version with hardcore inserts, but there is no suggestion that any of the credited cast participated in it.
