This animated short gem was part of the musical feature Make Mine Music.
The song was written by Harry Creamer and Turner Leighton. It was performed by Benny Goodman's quartet, with Goodman on the clarinet, Teddy Willson on the piano, Sid Weiss doing bass and Cozy Cole on drums.
I love this short. It features nothing more than than a variety of anthropomorphic musical instruments interacting with each other and dancing to Goodman's music. I would call the animation semi abstract, with exhilarating timing and color styling.
I am not sure who sketched these story/color continuity pages, but they are lovely and make for good study as far as how Disney was breaking down a piece of jazz music with entertaing visual results.
Here is a magazine article featuring tis segment from Make Mine Music.
