Legend
Personally, I can find several references to this on IMDB, documentary blurbs, and other similar sources, but none cite actual sources, so it COULD be apocryphal. If it did happen, it was probably those stations situated in the more rural/conservative areas.
I’d be surprised if it EVER aired in Vidor, Tx., for instance...
I found at least a half dozen such statements but, given that they are worded remarkably similarly, you may well be right.
