Tim and Steve - Thanks for checking it out! Download the PDF, should solve your issue. I'm guessing you just read the webpage preview.

Steve - It's not a paper. See the note at the beginning ;) Was a one-off summary response to a journalist's questions.

Not saying those things were called chanties. Chanties weren't even called chanties most of the time! (most is called song or chant)--yet we read about unnamed songs and call them "chanties" because that's our name for that thing, expedience. Saying they are same form of song. A rose by any other name.

Didn't go into details on nomenclature, but I do that in the published 'The Execrable Term' article linked. Have another brief paper on non-sea songs at that Academia.edu site. Unpublished stuff. Haven't had time to put any of that in publishable form for last 3 years as I've been all about Punjabi music!!! :-)
