Lighter, I am in complete agreement with Research Rule #6. I just found it interesting that there was the idea out there that this shanty was sung as the "volunteers" were heading out to Mexico. Hugill mentions the possibility that the shanty was based on a shore ballad. I wonder if the "Song of the Memphis Volunteers" might fit. Pure speculation.

I need to go back and read a bit more about Mr. Kelly's diary on board the "Algoa Bay". I'm not sure of the dates of that voyage.

I've been trying all day to remember/figure out what that 1868 article on shanties that you mention is and where it is. Can you refresh my memory on that. Thanks.
