Music by Jerome Kern, lyrics by B.G. "Buddy" De Sylva, from the Broadway musical "Sally," 1920. Sung in the musical originally by Jazz Age superstar Marilyn Miller, touchingly reprised by Judy Garland(playing Marilyn Miller) in the Hollywood Kern biopic, "Till The Clouds Roll By"(1946) and the title song for the 1949 Marilyn Miller biopic of the same name.
