Be sure to . . . drink . . . your . . . Ovaltine. Ovaltine?! It's a crummy commercial!
I'll add something to the radio show conversation. I'm fairly well versed in American shows, but not so much British. If you want to hear some good Yankee material then follow this link and download the old fashioned radio widget—if you have a Mac. If you have a PC you can still listen but you can't have the cool widget. Sorry.
My favorite show is The Jack Benny Show. He and Rochester were so funny together! And I love Fibber McGee and Molly. The link I gave has tons of mystery programs and old commercials as well, so give it a try. Enjoy!
