Thanks, DrPrice.

So the "Marco Polo" verse comes out of Davies' writing then, or what?

Although Hugill was in conversation with Davies, Hugill's tone does not suggest to me that he understood the Welsh lyrics to his three Welsh chanties (Mochyn Du, Hob d Deri, Rownd yr Horn) as composed by Davies.

What sources tell us that Welsh crews never sang Welsh-language chanties? And why would that be the case if they are using the language for normal things? Seems like it would be the opposite way.
