The copyright is 1962, well after the time that Lloyd is suspected of working up some kind of "Come down with your roses" shanty to produce BBR. Both Hugill and Lomax accepted BBR as an old shanty, and as Mr Elder worked with Lomax perhaps the reference to an analogy in his book is due to him. Particularly as Mr Elder was able to quote all the collectors who had something to do with an early "Roses" shanty.

I think it's very interesting too that the children's game which apparently provided the original song might have come from Scotland. If so, it's another astonishing example of how songs sometimes migrate and evolve from one culture to another. Reminds me of the theme from Dvorak's "New World" symphony, which again started out as a Scottish tune, a lament for the pipes, became a spiritual in the Deep South, and ended up being played in concert halls around the world.
