To the reader who contacted me about Jimmy Gallager's Band-

You should contact the department of Tennessee state parks and talk to them. They put up the kiosk at the entrance to the Harpeth River park off McCrory Lane in Pegram that mentions the band. I did some looking around on the Internet when I wrote this. I think Gallagher had some Vanderbilt connection as well, and had a hand in writing the Vanderbilt Commodores fight song. if memory serves.  I hope this helps!
