The lyrics read as a very modern and non too distinguished addition to a fine and much loved tune recorded by Planxty in their glory days. I can't just now put my hand on the 19th C 'fairy tale' volume containing the Irish story of the battle of the two fairy hills, one big and one small, who played at the hurling, but the losing team used magic and terrible damage was caused to the countryside. I've a notion that the human musicians called to play for the game played the tune in question to calm the tempers of the players, but I may be inventing or interpolating that.
