Poor Devil resulted in Davis being offered an honorary second-degree membership in the Church of Satan, which he accepted after inviting Anton LaVey and crew to a concert. They gave him the membership certificate, card, and Baphomet medallion. He'd had an interest in the occult for awhile at the time, according to his book "Yes I Can".
Hard to tell based on clips alone, but it appears to be a crime that Poor Devil never got approved for series. I know I'd have watched the shit out of that.
