September 19, 1931 –
Paramount released the Marx Brother’s third film, Monkey Business on this date.
Early in the movie, The Marx Brothers – playing stowaways concealed in barrels – harmonize unseen while performing the popular song Sweet Adeline‘ which is traditionally performed with four singers. It is debated whether Harpo Marx’ singing voice was used in the soundtrack. There is also an unconfirmed rumor that he provided the puppet master’s voice in the Punch and Judy show.
