Thanks for that information, Anglo.  It's interesting to see how even two or three removes can result in noticeable changes, many of which are typically oral-formulaic in nature ("for to take", "many's the", "the doctor he", and so on).  I don't know if He Came From The Mountains was ever released in America, and it's been unavailable here for years (courtesy of the infamous "Celtic Music") so comparison with the original would have been difficult; indeed, many people seem to think that the song is traditional.  Incidentally, did Roberts and Barrand know that it was a recently-made song, or did their source tell them that it was traditional?
