Here y'are mary o'mine... ^^

The song is actually called "Far am Bi Mi Fhin" but it's what Cookie Rankin sings while Natalie Macmaster is playing The Drunken Piper.

Seist
Far am bi mi fhin is ann a bhios mo dhochas
Fam am bi mi fhin is ann a bhios mo dhochas
Far am bi mi fhin is ann a bhios mo dhochas
Far am bi mi fhin bidh mo dhochas ann

1
Siubhal air na cladaichean 's a' coiseachd air a' ghainmich,
Siubhal air na cladaichean 's a' coiseachd air a' ghainmich,
Siubhal air na claeaichean 's a' coiseachd air a' ghainmich,
Far am bi mi fhin bidh mo dhochas ann

2
Theid mi fhin is Sine null gu taigh a' phiobair,
Theid mi fhin is Sine null gu taigh a' phiobair,
Theid mi fhin is Sine null gu taigh a' phiobair,
'S ni sinn brod an ruidhle leinn fhin air an lar.

3
Is mar d'thoir am piobair puirt dhuinn airson ruidhle
Is mar d'thoir am piobair puirt dhuinn airson ruidhle
Is mar d'thoir am piobair puirt dhuinn airson ruidhle
Tha fidheal aig a' chiobair is piob aig a' cheard.

There's another verse in the full song but Cookie doesn't actually sing it.
