Really, blackface?

I decided to watch Do Not Adjust Your Set on Amazon Prime due to half the cast going on to Monty Python afterwards. The show had a regular musical segment featuring the Bonzo Dog Doo-Dah Band and in one episode there they were, dressed like African natives in blackface singing about a monster. I was internally cringing and thinking "really? this shit is happening in the 60s?" The worst part though, is that several website are labeling the show as a children's program so it's "blackface for kids!!!"

A word of warning for any python fans that are looking for other shows starring the same cast members.
