Dimphne,
I hope these are the words you are looking for. I have heard this song referred to as " An Buachailin Bawn" and also " An Buachailin Donn"

My true love he dwells in the mountain
Like a war eagle fearless and free
By the side of the low-tuning fountain
That wanders through sweet Annalee
His soul has more valour and honour
Than a King with a palace and crown
For the blood of the race of O'Connor
Fills the veins of my Buachaillin Donn

Soft" Cead mile Failte" I give him
When he comes every Sunday to me
And what can I do but believe him
When he whispers " A Chuisle mo croi";
For his look is so truthful and tender
From his bright roving eyes of dark brown
That I'm sure e'en a lady of splendour
Would be coaxed by my Buachaillin Donn

My father has riches in plenty
And suitors for me in his eye
But Oh, let my age come to twenty
If I don't bid them all the Goodbye
For I sigh for a life in the mountains
Far away from the dust of the town
With a song of the low tuning mountains
And the love of my Buachaillin Donn

Slainte

enjoy
