One of the first OTR shows I had heavy exposure to, was The Great Gildersleeve on KFI, Sunday evenings in the mid-1970s. I made cassettes of many of them, but I haven't heard those in decades. Perhaps they were syndicated by Charles Michaelson? They seemed to have replaced the original music, narration (set-ups of the situations) and of course the commercials, with a different narrator and a quite annoying "lite" musical theme. Unfortunately, that theme still plays in my head. I've wondered if the reworking was done for Armed Forces Radio, or just the intended syndication audience. I suppose it was meant to freshen-up those 1940s shows for the "modern" audience.
