I miss the variety shows. I liked nearly all of them... even though some I didn't see that often.
I suppose the one I saw most was Carol Burnett.
One I remember that I had almost no interest in, at the time.
My parents, and their friends, were on fire waiting for Elvis to appear on the Ed Sullivan Show. I had no idea who Elvis was, nor did I care, but all the adults around me thought it was the biggest event in history.
One I did not watch was Sonny and Cher... but for no particular reason... can't recall why but I suppose I just never got around to it. Probably busy being a Teen.
Dean Martin I watched semi-regularly. Same with the Smother's Bros., and Laugh-In. - JamesJM
