An' O! my Eppie,
My jewel, my Eppie!
Wha wadna be happy
Wi' Eppie Adair?
By love, and by beauty,
By law, and by duty,
I swear to be true to
My Eppie Adair.
An' O! my Eppie,
My jewel, my Eppie!
Wha wadna be happy
Wi' Eppie Adair?
A' pleasure exile me,
Dishonour defile me,
If e'er I beguile thee
My Eppie Adair!
