Interesting that 'Cheerily Men' gets by far the most mentions. We have had this before in the British revenue cutters.

Do we have some text to 'Captain gone ashore'? I seem to remember Gibb has several early references to this one. The others are probably just mentions of shore songs being tried out and then discarded.

Also interesting that some of the mentions of worksong use refer to steeving hides, quite similar to screwing cotton.

Also of note is the reference to Americans (likely African Americans) using the songs to greater effect. A lot of Gibb's early references to the earlier songs are of African American rowers, in e.g., the Georgia Sea islands.
