I gaed a waefu' gate yestreen,
A gate, I fear, I'll dearly rue;
I gat my death fraé twa sweet een,
Twa lovely een o' bonnie blue.
'Twas not her golden ringlets bright,
Her lips like roses, wat wi' dew,
Her heaving bosom, lily-white,
It was her een sae bonnie blue.
She talked, she smiled, my heart she wiled,
She charmed my soul, I wistna how;
And aye the stound, the deadly wound,
Cam frae her een sae bonnie blue.
But, spare to speak, and spare to speed,
She'll ablins listen to my vow;
Should she refuse, I'II lay me dead
To her twa een sae bonnie blue.
