My mother passed away ten years ago this month, and along with many other people of her generation she loved watching CBS on Saturday nights. Especially the lineup that began in the 1973-74 season, with Mary Tyler Moore, followed by Bob Newhart and Carol Burnett. The color coding on this chart from Wikipedia shows that Burnett was only a top 30 show, but I think Mom enjoyed it more than anything else on television.
I was starting college at the time, and watched next to no television, but if I had I would have enjoyed seeing Petula Clark as a guest on the Carol Burnett Show. Pet makes her appearance at exactly 14 minutes into the show. She returns halfway through for a funny a soap opera parody (except Tim Conway’s bit is too long) and a duet with Carol.
Season 7, Episode 9
Airdate: Saturday, Nov 10, 1973, 10:00 PM
Just last night the SNL 40th anniversary show included this soap opera parody.
