I recently have discovered the Bob Hope Radio show which ran throughout the 30's, 40's and 50's. Most of the shows online are from the 40's and 50's. They are really funny and my favorite ones are the ones that he did from army bases in the us that aired on the radio for everyone to hear. There are some great guest stars. My favorite being the one with Humphrey Bogart, but I could not find that one for download only streaming media. I am posting some for all of you to enjoy.
Here are some links for many, many more shows to download and listen too.
