Thanks for the heads-up, Gibb. Great article.

Before the age of the Internet, new words from non-literary sources often took many years, even decades, to enter print with any frequency. It seems certain, for example, that "O.K." effectively originated as a lame joke in a Boston newspaper in 1839, but it wasn't till after the Civil War that it began to appear much in print. It took even longer to become current in novelistic dialogue.

All of this is entirely consistent with your suggestion - based in part on W. Clark Russell's recollection - that "chantey/shanty/chanty" was not a word known to the majority of deep-water sailors (especially not British sailors) before the late '60s or early '70s.

The same journal published my first article back in - well, let's just say "back in the day" and leave it at that.
