who wrote make them laugh and be a clown
Be a Clown. Be a Clown is a song written by Cole Porter for the 1948 film The Pirate. The song was performed twice in the film: first by Gene Kelly and The Nicholas Brothers and then at the end of the film by Kelly and Judy Garland. It was also sung in Mickey's Fun Songs: Let's Go To The Circus although some of the lyrics were changed.
Only two songs were written especially for the film: Moses Supposes was written by Roger Edens, Betty Comden and Adolph Green; Make Em Laugh was written by Arthur Freed and Nacio Herb Brown especially for Donald O'Connor.
