Well, I gave it a try. YouTube link.

I am by no means certain that Hugill's published melody needed "correcting," as I have done, but some things are suspicious enough about it that I decided for it.

Specifically, I believe that the grand chorus is notated at twice-as-fast the value it should have been (i.e. it should start with a dotted half note instead). Basically, the ratio of notes per beat seems to be out of whack in places (I have found this to be pretty common in this book). The verse was at one ratio, while the start of the grand chorus shifted to another, and then back again at the last measure of the song. Hugill's notation has 13 bars. I've normalized it to 16.

Again, I could be wrong, but this way made the most sense to me -- not that chanteys always necessarily make conventional sense.
