What was daytime TV talk like in the 1970s?

I'm trying to remember, as I see that Mike Douglas just died. See him in action here, talking to Frank Zappa in 1976. And here he is with Johnny Cash... and Don Rickles. Cash calls Rickles a "great spiritual leader," and Mike asks Cash if he always wears black.

John Lennon and Yoko Ono co-hosted the show for a week. Here's what Douglas had to say about one of the guests they picked out, Jerry Rubin:

He just got on my nerves. It sounded like this guy hated the president, the Congress, everyone in business, the military, all police and just about everything America stands for.

RIP, Mike.
