You Don't Know What Love Is

"You Don't Know What Love Is" is a popular song of the Great American Songbook, written by Don Raye (lyrics) and Gene de Paul (music) for the Abbott and Costello picture Keep 'Em Flying (1941), in which it was sung by Carol Bruce. The number was deleted prior to release.

Universal later added the song into the Raye/de Paul score of one of its B musicals, the 60-minute Behind the Eight Ball (1942), starring the Ritz Brothers and re-teaming Carol Bruce and Dick Foran from "Keep 'Em Flying". "You Don't Know What Love Is" was again sung by Carol Bruce; it was her third and final film until the 1980s.
