There was some interest in a couple of the songs I led last Saturday, and I promised to post some details, so here's what I know:
The song Nellie J Banks was written by Lennie Gallant. There's a rather rollicking version of it done by the Killicks that you can find on You Tube, and I've toned it down a bit for the way I like it. The Nellie J. Banks was an actual rum runner of some note, and was captained by Isreal Lillington. Her rum running days were ended when she was captured by the government on August 9, 1938.
I don't know who actually put "Hang On Jon" to music, and the only person I've heard do it is Bob Stuart, who did it at the 2011 PMFF, so it may have been him. The story line is derived (but abbreviated) from the children's tall tale John Tabor's Ride, written by Blair Lent in 1966 (there is another children's tale of the same name by Edward C Day, but that weaves a different story line). I don't know why Bob changed the name from John to Jon, but he seems to have. You can hear him do this song on his reverbnation page. I'll try to contact him to ask if he wrote it.
