I was surprised to find out there was a radio sitcom starring film actors Ben Lyon and Bebe Daniels Lyon, and that it apparently lasted to at least 1961. Impossible, you say? (That's what I said, about the late end date.) Then I found out it was on the BBC. Britain kept on longer with some things, such as network radio, steam locomotives, and living without butter after WWII.
I just started listening to some of the shows. One from November of 1950 has the same plot as a Burns and Allen from February of 1949. Bebe (Gracie) thinks Ben (George) should become a doctor, and volunteers his services at a hospital. He thinks he's supposed to do "his act" for a charity show, but the doctors want to do a risky experiment on him. And it was just a couple weeks ago I told a friend about that "three-way mix-up" storyline as one of my favorite B&A episodes...
I wonder if... that is, I HOPE... there was some arrangement about reusing plot lines. In those days, few listeners of U.S. radio were likely to hear BBC, so it made sense.
