Me too. Especially as I had just read that section of "Fakesong" and recognised that some rebuttal of what is said required detailed knowledge.

Some sticks with which Harker beats Sharp rely on Sharp's own writings. It seems a fair point that many who sang for Sharp were not peasants by any definition. Similarly it seems to be Sharp's own accounts that indicate that some songs may have come from early 19C 'commercial' sources. All credit to Sharp for recording information that went against his own theories. Transparency rather than fakery. I wonder if Sharp's story for the lecture circuit and lobbying for folk song in education avoided some of the loose ends in his actual collecting (and recording for posterity).
