It looks like the linked reference you are referring to, http://www.precisionproductions.com/whalers/docs/Shantybook2009Proof.pdf
is no longer on the web.

It looks like the link was to the old website of the Wareham Whalers, which is now located here:
http://www.wareham-whalers.org.uk/index.htm
They have song lyrics on the site, but none seem to correspond to the chorus above.

I suspect that the "precisionproductions.com" link from the old thread was probably a link to the "2009 Festival Song Book" that these folks are selling:
