My mom was a faithful viewer of his show every Saturday night and I don't honestly recall hearing him sing it on the show. Though I could have missed it because I wasn't always home every Saturday night. However, if he had sung it, I think my mom would have told me because she was also a DS fan. But hey, that was nearly 50 years - maybe she did tell me and I just don't remember. But the interesting thing is that I've seen where getTV runs a lot of his old shows, so who knows, if I keep track, maybe we'll find out for sure...
