Nobody's Sweetheart dancer?
Right after Mae Johnson finishes "I LOST MY SUGAR IN SALT LAKE CITY" an unidentified man jumps in and dances to "You're Nobody's Sweetheart Now". Does anyone know the dancers of the period well enough to identify him?
... IMDB's cast listing includes Henry Phace Roberts (uncredited) without specifying his part; he's a dancer, but is he THAT dancer?
(Note: this isn't currently in the IMDB soundtracks listing; I'd live to add it if I can figure out who the dancer is)
