@eurocelticyankee,
I am. Back when I was twelve and quarantined, literally, in my bedroom with scarlet fever, I listened most of the day, for weeks, to the radio. I might have heard the last Shadow show; at least I never heard it come on again. Mercedes McCambridge was stuck with the murderer in an elevator (or something like that), then came the end sounds, something like "tune in tomorrow for the next episode"..
