Loved Dick Cavett! There are some Youtube videos of a few of his interviews – classic!
Kinda funny that nobody has mentioned Leno.
Anyone watch David Frost? Phil Donahue? Tom Snyder? OK… off to take my Geritol now…
Did not like William Buckley’s Firing line. He seemed so pompous.
I knew Tom Snyder. He knew me but not by name. I used to run into him in town and we talked several times. He was a very nice guy. I liked him a lot. He wore clothes that looked like pajamas in public. 
I remember David Frost and Phil Donahue. Actually, I ran into Phil Donahue too. Just once though.
I don’t want to pretend I know that many celebrities. I don’t. A friend’s son works on the James Corden show. I bet he knows some celebrities. 
Leno doesn’t do much for me. I liked Letterman better.
Colbert’s dancing wasn’t the problem, it was his hideous vertically striped pants! He must have chosen them for how bad they made him look.
