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.
