Hey Barry!

Mayhap you can fill in the song to this chorus:

Sail on Bill McCoy, Sail on Arathusa(phonetic), Runnin' the rum from Nassau town to the mouth of NY bay.

It's not a chanty as such, but I learned it at a chanty sing and never learned the verses, as we didn't stay in the city long enough to go to enough sings to learn all the songs well. It's also been driving me nuts!
