I agree with the Sonny and Cher show. The Smothers Brothers Show. Gosh, there were SO many, though they were mostly short-lived. I remember the Carol Burnett Show, Barbara Mandrell and the Mandrell Sisters, Dean Martin (WOW! Who could get away with THAT now??), Tony Orlando and Dawn, the Carpenters, Captain and Tennille, the Brady Bunch (HA!), Tom Jones, Dick Cavett, and Andy Williams. There was also the wonderful, wonderful bubbles of Lawrence Welk, though I didn't sit down to watch it, just passed by while my mom did.
The Carol Burnett Show was awesome! And the Sonny and Cher show and the Smothers Brothers were great, too. Jeez, can you imagine if we had shows like this nowadays? They'd be so crude and trashy, we wouldn't watch them anyways.
