IMDb claims that John Fulso (dates unknown) played one of the chorus boys in MGM’s Dancing Lady. There does not seem to be any other information about him.
However, a John Fulco performed in Broadway productions, usually in the ensemble, throughout the 1920s and 30s. There is a reasonable chance that this is the same person, in which case the stage credits indicate that he was as much of a singer as a dancer. He also had a straight role in a 1931 mystery melodrama called Gray Shadow.
