Just a comment. After hearing Ives' version, I believe it likely that he referenced Doerflinger's book for his tune -- rather than, for example, following Lloyd's. I do think there was an influence of Lloyd, too (or, some common version doing the rounds of folk clubs).

And FWIW I do still think Lloyd referenced Doerflinger. But this would mean a parallel trajectory...even if Lloyd's did win out as the most influential.

By chance, does anyone reading know if Burl Ives could read music well/ at all?
