"Woo-Woo" is the B-side of the 78-rpm jazz instrumental single recorded on February 1, 1939, by Harry James and The Boogie Woogie Trio.

Shortly after leaving Benny Goodman's band and before starting his own band, James entered the studio at the suggestion of Columbia Records producer John Hammond.

James was paired with Albert Ammons (on "Woo-Woo") and Pete Johnson (on the flip side's "Boo-Woo"), the two foremost practitioners of boogie-woogie piano, which was enjoying a substantial revival at the time.

They were accompanied by Johnny Williams on bass and Eddie Dougherty on drums.
