Musical game shows need to be lighthearted and not very intellectual these days, as The Singing Bee proves. (Apparently, though, they needed to be that way in 1966, too, judging by the success of the show.)
One show I thought should have lasted a bit longer was 1975's
Musical Chairs. That was similar to each of the current shows in that most of the questions were about filling in missing lyrics. There was enough variety on the show to make it interesting as some of the questions were about who sang the songs themselves or what movies they were in, etc.; and having celebrities do most of the signing satisfied the appetite for celebrity-filled game shows back then.
For me, that was a lighthearted fun way to spend a half-hour. I almost think I appreciate that show more today than I did back then - the one episode in the trade curcuit is a good one featuring a young Irene Cara and the group The Spinners.
