Now, Young Emma/Young Edwin in the Lowlands Low / Edwin , interesting song indeed. Martin Carthy sings a version of this song on the 1992 Fellside Records release, Voices: English Traditional Songs ( I have this record in my collection). Peter Bellamy made a recording, singing it unaccompanied, in 1979 as Edmund in the Lowlands for his album Both Sides Then.

Both Carthy's version and Bellamy's version are American in origin, Carthy's from the Ozark Mountains, and Bellamy's from the singing of Gale Huntington of Martha's Vineyard.
Oh and Steeleye Span do a shortened version of the song on Now We Are Six (also in my record collection)
