Thank you very much, Sian, for looking (and thanks Pip for suggestion).

It seems then that maybe these chanty verses turned up by Hugill were rather incidental or one of a kind. And I presume no one has worked up a chanty version using Hugill's collection.

A related question: Does someone know where the current chanty version's verse, "I'll sing bass/you sing solo", originates? What/who is the particular song collection or artist that introduced it?
