I'm sure there's been much discussion on "She Moved Through the Fair" but don't know if this variant has ever been posted. It's from a recording of Paddy Tunney I recently acquired.

I ONCE HAD A TRUE LOVE

I once had a sweetheart, I loved her quite well
I loved her far better than my tongue could tell
Her parents disliked me for my want of gear
So adieu to you Molly, since you are not here

I dreamed (pron.drem-ed) last night that my true love came in
So softly she came that her feet maid no din
She stepped (again 2 syllables) up to me and this she did day,
"It will not be long, love, till our wedding day"

Oh, if I was a fisher down by the seaside
And my love was a salmon coming in with the tide
I'd cast my net wide and my love I'd ensnare
I would bring home my Molly, I vow and declare

Or if I was a blackbird and had wings to fly
It's on my love's bosom this night I would lie
In a grove of green laurel I would lay her down
And with my strong wings I would her surround

Or if I was in yonder valley where the small birds do sing
And no one to be near me, 'tis I'd cry my fill
Since the notion it took me to have my own will
Sure my own rod is sorest and does beat me still

Then adieu to you Molly, adieu to my dear
Adieu to you sweetheart since you are not here
In a grove of green laurel I'll there make my moan
And I'll think of you, Molly, when I am alone
