Part of the archive was this script for Rudy Vallee‘s “The Drene Show” which was a 30 minute radio program in the early 40s. This particular script revolves around Rudy trying to steal a secret recipe from Don the Beachcomber to make his place more popular. Rudy was a friend of Donn’s and there is at least one image of him in the archive at the Chicago location dropping a tip into the charity donations box with Donn.
There wasn’t much to use in the book, but it did say in the text it was in 1946, and I wanted to search for info on the show in general. That’s when I found that it was recorded. The episode was aired March, 21st, 1946 and titled “My Tane” for the song. Here it is for your listening pleasure: “My Tane”. Donn appears about the 18 minute mark.
