A Phúca,

To me, anyway, "folk etymology" means at least lacking in evidence and at worst, contrary to evidence.

Incidentally, I was talking to Frank Harte last night and asked him about "Monto". He reckoned it was even later than my '40's estimate - he thinks it was written for a John Molloy show as late as late '50's or early '60's - around the time Luke Kelly came back from Engalns.
