Listening to the MIDI file, I noticed a striking similarity to a song by that June Tabor recorded, "The Plains of Waterloo". The first two lines of the second sections are nearly the same. The first two lines of the first sections also have a similar sound, though the correspondence there is less pronounced.

Is this a case of someone "creating" what they really remembered subconsciously from somewhere else? I know when I've done this, I tend to then overcompensate with innovation (as it sounds to me happened here: the remaining parts of the tune seem forced rather than organic.)

And can someone clarify: does the MIDI file correspond to McConnell's version or to Clifford's/Dennehy's? And did Dennehy borrow the tune or compose it?
