OK Paul, the following is as per the original.

MY LAGAN LOVE

Where lagan stream sings lullaby
There blooms a lily fair:
The twilight-gleam is in her eye,
The night is on her hair.
And, like a love-sick leanan-sidhe,
She hath my heart in thrall:
Nor life I owe, nor liberty,
For Love is lord of all.

Her father sails a running-barge,
'Twixt Leamh-beag and The Druim;
And on the lonely river-marge,
She clears his hearth for him.
When she was only fairy-high
Her gentle mother died;
But dew-Love keeps her memory
Green on the Lagan-side.

And oft-times, when the beetle's horn
Hath lulled the eve to sleep,
I steal unto her shieling lorn,
And thro' the dooring peep,
There on the crickets' singing stone
She spares the bogwood fire,
And hums in sad, sweet under-tone
The song of heart's-desire.

Her welcome, like her love for me,
Is from her heart within:
Her warm kiss is felicity,
That knows no taint of sin.
And when I stir my foot to go,
'Tis leaving Love and light
To feel the wind of longing blow
From out the dark of night.

Repeat first verse.
