From the 1939 short "The Dipsy Doodler" by Larry Clinton and His Orchestra, featuring Bea Wain and the Philharmonicas. The song was written by Harold Arlen and Theodore Koehler and debuted in the 1930 show "9:15 Revue".
Dance routine by (not) Lee Wiley and (possibly) Marie Hartman from Woody Herman and His Orchestra's self-titled 1938 short. (See comments for discussion of the identity of the dancers.)
