Phil, I have followed this and similar threads with increasing bafflement. I simply cannot fathom just what it is you are trying to say, whether it's about shanties or maritime work songs in general.

It's great that you are researching maritime work song, and looking at other periods of time and other cultures than simply the 19th century Anglo-American shanty tradition. However you appear to be using Mudcat mainly as a dump for your raw data, which is untranslated and often presented without comment. When you do comment, it is often written in such an oblique style that it is unclear what your point is.

May I respectfully suggest that you complete your research and then present us with your findings? We might then be able to have an interesting and fruitful discussion, which none of the current threads seem to be able to provide.

Looking back, I see that Steve Gardham requested something similar as long ago as July 2020.
