Thanks, Booter, for directing us to those examples from Carpenter. Astonishing that the ballad was still going strong in 1930, even though Greig doesn't seem to have found it.

There are three Carpenter versions with tunes. Mr Campbell's is rather like the tune for 'Young Allan', while Mrs, Campbell's is a lot simpler and more repetitive. Both are modal with a gapped scale. Bell Duncan's is pentatonic (no 4 or 7) and major, again fairly simple. None of them looks to me much like the one in Chappell, though it's just occurred to me that Chappell's is similar to that of 'Lucy Wan' as published in Lloyd and Vaughan Williams' Penguin Book (from Mrs Dann of Cambridge). Good news for Dave Rado in his search for an English tune since, even if Chappell did copy it out of Motherwell via Rimbault, it does appear that it saw service as a generic ballad tune in England!
