I recall seeing some version of the Dean Martin Show on TV.
Unlike most TV comics, Dean was always well dressed every week. I think he usually wore a Tux unless acting out a skit.
I’ve heard that Dean would almost never come to the rehearsals early in the week. He would simply show up when it was time to shoot the episode and improvise most of his dialog. By that time(late 60’s), he had been a top Hollywood name for over 30 years, so he knew how a program was usually put together. It was kind of a Playboy inspired version of He-Haw, now that I think about it. Fun show.
His contract let come to work on the day the show was taped in front on an audience , he read cue cards, never rehearsed so he was as surprised at things as the audience was. At the time he was the highest paid TV actor on TV, earning then around $300,000 an episode.
