The singer from whom this song diffused was Peter Donnelly of Castlecaulfield, Co Tyrone. He was recorded by the BBC in July 1952 - they thought it came from a ballad sheet but I've never seen such a sheet. The usual transcription has some major errors - the line that Martin Nail cites above has neither died not skived - neither of which make any sense in the context of 'And the more they ... on me. the more I will say. I hear the word as 'jibe' meaning 'object to'.

My transcription of what Peter sang is below with a note I wrote at the time of transcription:

The lass on the brae - Peter Donnelly, recorded at Castle Caulfield, Co. Tyrone.

As I roved out on a fine summer day
The fields were in blossom, and the meadows were gay
I spied a wee lassie tripping over the green
And I took her for Helen, that Grecian queen
That Grecian queen, oh, that Grecian queen
And I took her for Helen, that Grecian queen

She's admired by others, I know them right well
Every morning to view that sweet spot where she dwells
Beneath the hawthorn that blooms on yon hill
May she never marry, but think on me still
But think on me still, but think on me still
May she never marry, but think on me still

Ah me parents jibes on me, and it's all for their sake
And oft times it causes my poor heart to break
But the more they jibe on me, ah, the more I will say
That there's none will be mine but the lass on the brae
The wee lass on the brae, the wee lass on the brae
For there's none will be mine but the lass on the brae

Ah when Phoebus declines o'er yon low far-off sky
It is off to my darling like lightning I'll fly
If the night was as long as a long summer's day
I would cheerfully sit with the lass on the brae
The wee lass on the brae, the wee lass on the brae
I would cheerfully sit with the lass on the brae

Ah so fare you well, darling, I love you the best
And may you be happy and may you be blessed
And may you think on me, ah when I'm far away
For there's none will be mine but the lass on the brae
The wee lass on the brae, the wee lass on the brae
For there's none will be mine but the lass on the brae.

Peter Donnelly was recorded by BBC who noted.
