I’m not quite sure exactly which TV show this spot is promoting. A group of lovely, talented young women known as The Golddiggers first appeared on The Dean Martin Show in 1968. During the summers of 1968, 1969 and 1970 they headlined their own summer replacement variety show. There was also a syndicated series, plus U.S.O. tours and other performances. Whew!
If I had to guess, I’d say this promotional spot was for syndicated series. Check out the official, authorized website for the group here.
