I found a quote from the song at the website of the Clare Champion, a regional weekly newspaper:

There are places of fancy, of fame and renown,
But my choice is my birthplace, my own little town,
Snugly nestled and happy with no worry or care;
That's our town Ennistymon on the west coast of Clare.

The author of that web page says "one of our best loved local songs ... and it is as popular today as when written over 30 years ago."

I suppose you could try contacting them, too. Look here.
