Somehow, I remember seeing this clip before!
Darlings, just a quick song to kick off the final week of September. This is Cab Calloway’s take on “St. James Infirmary Blues” from the 1933 classic Betty Boop cartoon, “Snow White.” The wildly imaginative animation was created by rotoscoping Cab Calloway’s performance, resulting in the short being named one of the 50 Greatest Cartoons and earning a place in the National Film Registry.
You can watch the complete Betty Boop “Snow White” cartoon on The Internet Archive.
