O my luve's like a red, red rose,
That's newly sprung in June:
O my luve's like the melodie
That's sweetly played in tune

As fair art thou, my bonie lass,
So deep in luve am I:
And I will love thee still, my dear.
Till a' the seas gang dry.

Till a' the seas gang dry, my dear,
And the rocks melt wi' the sun:
OI will love thee still, my dear.
While the sands o' life shall run.

And fare thee weel, my only live!
And fare thee weel a while!
And I will come again, my luve.
Tho' it were ten thousand mile!
