THE WEE LASS ON THE BRAE

As I as a-walking one bright summer's day.
Oh the fields were in blossom and the meadows were gay.
I met a wee lassie tripping over the green.
And I took her for Helen, the Grecian queen.
The Grecian queen, the Grecian queen.
And I took her for Helen, the grecian queen.

She's admired by many others and I know them right well.
Each morning to view the sweet spot where she dwells.
Beneath the arbour at the foot of yonder hill.
Oh may she never marry but think on me still.

My parents dote on me and it's all for their sake.
And its oftimes it causes my poor heart for to break.
But the more I think on her, it's the more I will say.
That's there's no one will be mine but the wee lass on the brae.

In faith there is a decline under yon forest sky.
And it's straight to the arms of my true love I'll fly.
If the night were as long as a long summer's day.
Then I'd cheerfully sit with the wee lass on the brae.

So it's fare thee well me darling, I love you the best.
And may you be happy and may you be blest.
And may you think on me while I am far away.
For there's no one will be mine but the wee lass on the brae.

The words come from the singing of several people - Patricia Flynn, Jim McFarland etc - and might well vary from printed versions, but I think they are approximately standard!
