Yes that was Jeff Richards, DRCHARLESPOGUE....I think MBARNUM had some information about him that he posted last week.....
He was also in THE OPPOSITE SEX. I know that his "bride" in 7B47B, happened to be the lovely dancer Julie Newmar. On her Cult TV Stars episodes she stated that she was distressed that because HE didn't dance, she didn't get to do most of the numbers. She said that he was a baseball player, a nice guy, and being given a push by MGM, but felt a bit out of place among all the dancers. She said he worked very hard to do what little dancing he could, but even after hours of rehearsal, he mostly stood to the side and clapped his hands.
He does some steps in "Goin' Co'tin'" and finishes up the Challenge Dance, but is out of his element.
But after all these years, Julie still despaired being paired with the non-dancing brother!
