I have almost 2 dozen versions of Sheath & Knife, but Helen Schneyer's is about the only American one....one of the best though. Jean Redpath said it too her several years to find her own way thru it after hearing Helen.
... This version is 'what people do' in mixing two or more old songs to make an essentially different story.

Child 16, mixed with Child 6 and 13... it's no doubt "Boiled in Lead's" own creation, so no other version is likely.
