Bonnie Mary Hay, I will lo'e thee yet;
For thy eye is the slae, and thy hair is the jet,
The snaw is thy skin, and the rose is thy cheek:
Oh! bonnie Mary Hay, I will lo'e thee yet.
Bonnie Mary Hay, will you gang wi' me,
When the sun's in the west, to the hawthorn tree?
To the hawthorn tree in the bonnie berry den?
And I'll tell you, Mary, how I lo'e you then.
Bonnie Mary Hay, it's haliday to me,
When thou art coothie, kind, and free:
There's nae clouds in the lift, nor storms in the sky,
My bonnie Mary Hay, when thou art nigh.
Bonnie Mary Hay, thou maunna say me nay:
But come to the bow'r by the hawthorn brae,
But come to the bow'r, an' I'll tell ye a' what's true,
How, Mary! I can ne'er lo'e ane but you.
