You don't know what love is: A very honest and dramatic lament with genuine melancholic lyrics as well as the blues influenced melodic line. Written, amazingly, for an Abbot and Costello movie. ( No the boys did not sing it to each other)
This is a far superior song to much of what passes today with barely literate utterings screamed at top levels by would-be divas. Cassandra Wilson is a great jazz interpretor who treats this song with the quiet intensity it richly deserves. Music by Gene DePaul, lyrics by Don Raye. They also wrote I'll Remember April , a favorite of jazz players and singers.
