Sarah Makem sang the "Oh, what a foolish girl was I" line in the fifth verse of "The Butcher Boy" as recorded by Diane Hamilton in 1956 and released on her Musical Traditions anthology "As I Roved Out":

In London city where I did dwell
A butcher boy, I loved right well
He courted me, and me heart away
And then with me, he would not stay.

I wish, I wish, but it's all in vain
I wish I was a maid again
A maid, a maid I ne'er shall be
'Til cherries grow on an apple tree.

I wish my baby it way born
And smiling on its daddy's knee
And I poor girl to be dead and gone
And the long green grass growing over me.

She went upstairs to make her bed
And calling up her mother said
"Get me a chair 'til I sit down
A pen and ink 'til I write down."

At every word she dropped a tear
And every line cried, "Willie dear.
Oh, what a foolish girl was I
To be led astray by a butcher boy."

He went upstairs and the door he broke,
He found her hanging from a rope.
He took his knife and he cut her down
And in her pocket, these lines were found.

Dig my grave wide large and deep
Put a marble stone at my head and feet
And in the middle, a turtle dove,
That the world may see I died for love.
