Slightly off the topic but this must be the place to ask this - 
Listening to an audiobook drama recently, in the story there was a 
live concert broadcast on a major NYC radio station in 1939. Someone 
(the private eye, star etc.) missed part of it and someone called the 
station and was able to get a copy of the program - the same day. 
Would this have been possible then? Wouldn't it have had to be the 
original transcription disc, if any were made? It is a work of fiction 
so this is more fact-checking than actual history, but could that have 
happened in 1939?
Thanks,
