I often listen to Internet radio stations that play old time radio programs. A few days ago, I heard the program, Command Performance, broadcast on August 18, 1942.
Command Performance was created for the US Armed Services. They took requests (as you'll hear) and booked acts that appealed to service men. Cary Grant was the guest host. Don Wilson (Jack Benny's protege) was the announcer. The first musical guest was Spike Jones & His City Slickers. I remember seeing them on television in the '50s. I've always thought they were hilarious.
