They were good. I admit to watching the Mickey Mouse Club.
Dick Clark's American Bandstand ran from 1952-1985. It was lip syncing but it was a big deal to get on the show. Where The Action Is was another show that ran for a few years, 65-67 featuring Paul Revere and the Raiders with guests and filmed clips. Dick Clark was behind that show. Soul Train ran for 35 years.
Of course there was Ed Sullivan but he was more variety. For the older crowd, there was Lawrence Welk, The Andy Williams show, Perry Como, John Denver, Moma Cass, The Osmonds, The Carpenters, country shows including Barbara Mandrel, Johnny Cash, Hee-Haw and a host of other shows and specials. Many Christmas shows.
There was a lot of music on TV when I start thinking about it. But the Midnight Special and the Concert shows were late night for the kids. I didn't like it when Helen Reddy was hosting.
