There lives a young lassie, far doon in yon glen,
And I lo'e that lassie, as nao ane may ken!
O! a saint's faith may vary, but faithfu' I'll be,
For weel I lo'e Mary, and Mary lo'es me.
Red, red as the rowan, her smiling wee mou';
And white as the gowan, her breast and her brow!
Wi' the foot of a fairy, she links o'er the lea
O! weel I lo'e Mary, and Marry lo'es me.
There lives a young lassie, &c.
She sings sweet as ony wee bird o' the air,
She's blythe as she's bonnie, she's gude as she's fair;
Like a lammie, as airy and artless is she;
O! weel I lo'e Mary, and Mary lo'es me.
There lives a young lassie, &c.
