Simmer's a pleasant time,
Flow'rs of ev'ry colour;
The water rins o er the heugh,
And I long for my true lover.
Ay waukin O,
Waukin still and wearie:
Sleep I can get nane
For thinking on my dearie.
When I sleep I dream,
When I wauk I'm eerie;
Sleep I can get nane
For thinking on my dearie.
Lanely night comes on,
A' the lave are sleeping;
I think on my bonie lad
And I bleer my een with greetin'.
Ay waukin O.
Waukin still and wearie;
Sleep I can get nane
For thinking on my dearie.
