The "Early May" Princeton story was based on a one-sentence description of the lost episode that I found long ago. It basically said "Young Indy meets Paul Robeson in Princeton" and I had to make up the rest.
The new "Late May" episode is based on the longer description in that starwars.com article with the Captain Kidd treasure hunt. It's all finished, but I've got someone proofreading/editing it for me and she's not done yet. I hope to have it up very soon.
