This one is wrong on sooo many levels. “Scrub Me Mama with a Boogie Beat” (1941) was produced by Walter Lantz, the man who created Woody Woodpecker.
The voice work was done by the great Mel Blanc (except for the sexy female singer, whose identity I’m unable to ascertain).
This was top-of-the-line Hollywood animation. But when television came along, “Scrub Me Mama” (along with other racial cartoons by Lantz) was banned... for reasons obvious.
According to Wikipedia, Walter Lantz didn’t understand the problem. “[W]e never offended or degraded the colored race,” Lantz said, “and they were all top musical cartoons, too.”
