In 1923 he appeared in an early DeForest Phonofilm short "A Musical Monologue," in which he played the accordion and sang.

He appeared in at least five Hollywood films including roles in "The Goldwyn Follies" and with Carmen Miranda in the 1943 musical "The Gang's All Here." On radio, he starred in his own series, NBC's "The Armor Jester."
