In 1943 he became a member of the Sons of the Pioneers (also a singing cowboy group), who were backing up Roy Rogers in his Republic films. That group did scores of radio broadcasts and transcriptions, and in 1945 he had his own show (I think it was on Sunday) called the "Ken Carson Show".
In 1949 he became a member of Tom Brenneman's Breakfast Club, remaining with it as it morphed into the Garry Moore radio show. I think that that show was on Mutual, but I'm not sure. In 52 Ken had his own radio show "the Ken Carson Show" (Mutual Network) sponsored by Camel Cigarettes. I've got some of the scripts to that show, they're pretty neat.
All that to say, I'm trying to track down any and all recordings of Ken. Sons of the Pioneers material is fairly easy to come by, but the others aren't. If anybody can help me know where to look to find any of them, I'd be delighted! There's quite an impressive listing up for Ken on the RadioGoldIndex site, but I've only found a couple shows that are listed there.
Thanks, and nice to meet you all!
