(I did find the other copies, but didn't think I needed to post all of them)
So we have no evidence that the song was NOT by Scanlan, as claimed, as the dates seem feasible. Just thought it was worth checking if possible.
Was the term Fenian Men in use before the 1867 uprising? If not, then the Nugent copy is later than that. And why would the name Sarsfield be replaced by a generic term?
