One of the most famous "Whistler" episodes is called "A Brief Pause for Murder," where a radio DJ makes a recording of his voice to be played during a station break as an alabi so he can go out and kill his wife...
While listening to this episode today, I noticed that once in a great while, the DJ sounded EXACTLY like Frank Nelson. However, he is the main character, yet it was only in one or two small places that I could recognize his voice. The end credits verified that Nelson was in the cast, but if it hadn't been for those few glimpses, I would have sworn it couldn't be him.
Has anyone else heard this episode? It was broadcast on 9-11-1949. If you have the resources, check it out! I didn't know Frank Nelson could sound so little like Frank Nelson!
