Blue Devil Blues
"Blue Devil Blues" is a 1929 blues/jazz standard by Babe Stovall. It was first recorded in November 1929 by Walter Page and the Oklahoma City [Blue Devils], with vocals by Jimmy Rushing. It is described as "not strictly speaking a blues, but a rather simplistic, old-fashioned minor-key piece" in the key of C minor.
The latter half of the tune, featuring vocals by Jimmy Rushing, is in a 12-bar blues form.
