I believe one of the songs you want is "The Shores of Loch Bran". It was recorded by Dolores Keane.

THE SHORES OF LOCH BRAN
Dolores Keane


Sit you down, loyal comrades
Sit you down for awhile
'Til I spend my last hours
Around Erin's green isle

Come fill up your glasses
And we'll drink hand in hand
For tomorrow I'll be leavin'
The shores of Logh Bran

There's my father and mother
You can now hear them cry
With their tears, be willin'
Would moisten your eye

But I will assist them
Please, God, if I can
Far away from lovely Erin
And the shores of Loch Bran

In the end, come in mourning
I will bid you adieu
To (Lithra, Drum Shamble)
And sweet Kerry too

But no matter what fortune
I might make far away
My thoughts shall be with you
By night and by day

My thoughts shall be with you
While ice course is spanned
Far away from lovely Erin
And the shores of Loch Bran
