Yesterday, I posted this video link to a Don Rickles performance and speculated it was from the early days of Showtime. Not so. Michael Kilgore informs me it's from Rickles, a 1975 CBS special with guests Jack Klugman, Don Adams, Michele Lee, James Caan, Michael Caine, Jack Palance, Elliott Gould, Bobby Riggs, Larry Linville and Loretta Swit. I vaguely remember that show. It had some excerpts from Rickles' Vegas act but it also had musical numbers of him dancing with a line of showgirls. It was very…odd.
