Some years ago, I stumbled upon an interesting video of a comedy skit which was very close to early Hip Hop from about 1980, but actually was from the late sixties/early seventies. I’m quite sure that it pictured a trial, with the guy doing the rapping embodying judge soandso. It was somewhere cited as an example of pre-Hip Hop, but I can’t find it now.
Looking into it further, Pigmeat was on the Ed Sullivan show, and he, Sammy Davis, Jr. , and Flip Wilson all performed the skit or variations on Laugh-In (which is where I was remembering it from). Might have been any of those you saw, but I can’t find a video online.
