How green the fields, the flowers so fair,
How bright the sun, that o'er us passes,
How useless these if that there were
Nae honest men, nor bonnie lassies.
Honest men and bonnie lasses,
Honest men and bonnie lasses,
Lang may live and happy be,
A' honest men and bonnie lasses.
God's noblest work's an honest man,
A bonnie lass by far's the fairest,
Of all that's fair in nature's plan,
And e'er to man will be the dearest.
Honest men, &e.
How happy, and how blest the man,
His days or nights can ne'er be dreary,
Who calls an honest man his friend,
And has a bonnie lass for's deary.
Honest men and bonnie lasses,
Honest men and bonnie lasses,
A' they wish and a' they want,
To honest men and bonnie lasees.
