Submitted for your listening pleasure is the Lux Radio TheaterÂs version of The 39 Steps with Robert Montgomery, Ida Lupino, Isabel Jewell, and Gene Lockhart. It aired on December 13, 1937. Unlike some radio broadcasts, this one is pretty clear and close to an hour long.
Update: I pulled the link to the file - just leave me a comment if interested
Also...at the end of the broadcast, Bob asks for your input on his next movie. Drop a card or a note to MGM, Bob, or the Lux Radio Theater with your choice:
1.) A light comedy
2.) A story with a social problem
I'll be sure to send my recommendation out in tomorrow's mail ;0)
