Kate Purcell sings SLÁN ABHAILE on her album "Shadows of You." It's called "traditional" but it doesn't feel like a traditional Irish song to me; it feels more like country-western.

Cathie Ryan sings the same song on the album "Cathie Ryan" (1997) but there it is credited to Dermot Henry.

Two samples at Allmusic.com yielded these words:

...The sun is down.
The moon is blue.
I faintly know
I'm missing you.
But(?) time will heal
This heart-felt pain
As soon as I
See you again
Slán abhaile [followed by some more Irish words I can't transcribe]...


Tommy Sands has a song by the same title on his album "To Shorten the Winter: An Irish Christmas with Tommy Sands." It's credited to Dermot Henry and Tommy Sands, but it doesn't sound like the same song as the one above:

...And in the darkness of the troubled time,
When lonely hearts were grievin',
It was comfort to a troubled mind,
Your songs of love and freedom.
Only love can let me set you free.
It knows no rhyme nor [reason?]...


Ratty Shoes also perform a song called SLAN ABHAILE on their album "Blackthorn" (2001) but I have no sample, lyrics, or attribution, so I can't say whether it's the same song as either of the above.
