Does Noel Hill sing? Or do you mean a "tune"?
Either way, I can't seem to find what you're looking for. I hope someone else can help.
Waitaminit! You don't happen to mean "Sidhe Bheag, Sidhe Mhor" ("Shee Beg, Shee Mor")? That's an air by O'Carolan, supposedly referring to a battle between the fairies living under two hills. The name means "Fairies of the Big [Hill], Fairies of the Little [Hill]".
If that's the tune, you'll find it all over the place, with either of the above spellings and many more. Here it is on thesession.org. I don't know about a Noel Hill CD, though, as I don't have them all.
It is a tune. There are no words to it.
Thanks for the other info but I am afraid that is not the one.
Regards.
Graham.
