Words by Raymond B. Egan & Gus Kahn, music by Richard Whiting, 1921. A Jazz Age classic, a mainstay in vaudeville, film musicals, even literature of the time. Written shortly after the end of the traumatic, watershed WWI, this song jauntily announced in both style and sentiment the new heedlessness of the Age, an understandable reaction to the horrors of the War.
Early (1917) Tin Pan Alley standard by George W. Meyer, Edgar Leslie, and E. Ray Goetz. Later, the title song for the successful 1942 film starring Judy Garland and Gene Kelly(his film debut).
