Poem:
O,my love is like a red,red rose,
that's newly sprung in June.
O,my love is like a melody,
that's sweetly play'd in tune.
As fair thou art,my bonnie lass,
so deep in love 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 with the sun!
And I will love thee still,my dear,
while the sands of life shall run.
And fare thee well,my only love!
And fare thee well awhile!
And I will come again,my love.
Tho'it were ten thousand mile!
