I really think I ought to add that I have a great admiration for BG. He was just about the first in the field in England and his Scottish predecessors and ballad editors of the past did lots of this 'editing' and claimed their efforts were straight from the mouths of the peasantry. This includes some editors with much bigger profiles than BG. The great pity here is that a shadow is then cast on the other material sent to Child by BG and most of this could be untampered with. We just don't know. The same goes for the bulk of the material in Child. Child himself was very good at spotting the suspicious material, but he had an impossible task so tried to include everything.
