Nothing too terribly notable about this week's Overnight offering. The subjects were a young fashion designer, the creator of a hotel for cats and an astronomer who had researched Stonehenge. Fritz Weaver was on the panel in place of Tom Poston, who was performing Bye Bye Birdie in Seattle.
Just about the most notable thing about the episode was the opportunity to date it precisely. Weaver was on stage in Baker Street at the time, plus there's a reference in the Stonehenge segment about 'today' being the first day of summer. That means this was the episode of Monday, June 21, 1965.
Let there be much rejoicing.
