Dick, I mentioned that it's pretty easy for me to make a midi from sheet music. Unfortunately, I don't have a copy of Bronson. If there were some way for me to view the book, I'd be more than happy to help with that.

I'd started doing the tunes for Hugill's Shanties From the Seven Seas, but as I was doing it for my own benefit, I didn't get very far. Still, it only took 5 - 10 minutes per tune. Probably less once I got rolling.

If you can think of a way for me to help you, please let me know. Phil, from the Bronson Project mentioned above used to scan the pages in for me to transcribe but that may be too much of a bother.
