This is going to cost you an hour but it's worth it. In 1961, KPFK radio in Los Angeles arranged a panel on comedy with Groucho Marx, Steve Allen and Carl Reiner. The moderator is George Fenneman, who was Groucho's sidekick on You Bet Your Life and also participating in the conversation were Cecil Smith, who was an entertainment reporter for the L.A. Times, and Robert Young, who was the star of the series, Father Knows Best. I'm not sure why Mr. Young was on the panel and it sounds like he wasn't sure, either.
It's a pretty good discussion, especially during those rare moments when someone asks a question and someone else actually answers it. Give a listen…
