History

"Cotton Tail" is a 1940 composition by Duke Ellington. It is based on the rhythm changes from George Gershwin's "I Got Rhythm". The first Ellington recording (4 May 1940) is notable for the driving tenor saxophone solo by Ben Webster. Originally an instrumental, "Cotton Tail" later had lyrics written for it by Ellington. Later, more lyrics were written, based on the 1940 recording, by Jon Hendricks, and recorded by Lambert, Hendricks and Ross. The 1941 Soundie gives the title as "Hot Chocolate", with "Cotton Tail" below it in parentheses and smaller letters, but this was likely done by the producer, as that title does not seem to appear anywhere else between the original record's release and this production. Slide Hampton's arrangement of "Cotton Tail" on Dee Dee Bridgewater's 1997 album Dear Ella won him the Grammy Award for Best Instrumental Arrangement Accompanying Vocalist(s) in 1998.
