Radio’s golden age..and it’s free for the asking. There are NBC news broadcasts of the landing at Inchon and many other events. I just got “Dimension X” a science fiction series that has radio plays from Ray Bradbury, Kurt Vonnegut and other great writers. I will put them on my website at Normeen.com.
Hermit’s Cave is good..and so is “Nightfall”. There are hundreds of radio programs available. Most of the stories are still viable. Alan Ladd in “Box 13”, about a writer who advertises for adventure. Rex Stout’s “Nero Wolfe”. Sam Spade, Gunsmoke, and others.
