One of my favourite love songs you'll find below. That I do not understand all of the story perhaps even adds to my liking of this song (but don't hesitate to fill in information if you have).
All I know about it is that Seamus Ennis has translated this song from the Gaelic, that Donal Óg means Young Donald, and that at least Al O'Donnell, Archie Fisher, The Furey's, The Sands Family and The McKenna Brothers have recorded it.
The version posted below combines the finest verses from two sources.

DONAL ÓG

If you should go far across the water,
Oh, take me with you to be your partner.
In that fair and nice land, you'll be well looked after,
And you shall sleep with the Greek king's daughter.

The first time I saw you on that Sunday evening,
Beside the altar where I was kneeling,
It was of Christ's passion that I was reading,
But my mind was on you and my heart was bleeding.

Oh, Donal Óg, you'll not find me lazy,
Not like so many of the high-born and rich young ladies.
I'll do your milking and I'll nurse your baby,
And if you were set on, I would back you bravely.

For you said you would meet me, but you were lying
Beside the sheepshed as the day it was dying.
I whistled first, then I started ailing,
But all that I heard was the young lambs wailing.

Oh, and come if you will, come when stars are peeping.
Rap at the door that makes no squeaking.
My mother will ask you to name your people.
I'll tell her you're a sire of the night winds weeping.

I got the first kiss and from no craven.
I got the second atop the stairway.
The third kiss came as down you laid me,
But for that one night I'd be a maiden.

Oh, as black as the sloe is the heart inside me.
Oh, as black as the coal is the grief that strides me,
As black as that boot print on my shining hallway,
Ah, it is you who blackened it now, forever and always.

For you took what's before me and what's behind me.
You took East and West when you wouldn't mind me.
Sun, moon and stars from my sky you have taken,
And God himself - or I'm much mistaken.
