Hi Guest,

(Note: the spelling is Maire Mhor.)

I don't know the song but here is a link to an a capella performance by Aoife of Cherish the Ladies:

Maire Mhor

I tried searching for the lyrics but I wasn't sure which version you want.

I found the Cherish the Ladies website so maybe you could contact them to request the lyrics.

This is slightly off-topic but one of my favourite Irish tunes is called Cherish the Ladies performed by The Chieftains. It's a rollicking tune and I love it.
