My transcription from the album "Will Fyffe" (2008), as found at Spotify:


SHEILA MACKAY
As sung by Will Fyffe

Last year on a trip to Glengarry
I called at a wee but-an-ben,
And there I discovered a fairy,
The sweetest wee lass in the glen.
As soon as my eyes fell upon her,
I felt I was under a spell.
I knew then I was a goner.
I wanted her all to mysel.

CHORUS: Sheila Mackay, the lassie I adore,
I love her as I've never loved another lass before.
Pure as the rose, her beauty makes me sigh.
I've shairly lost ma hairt to Sheila Mackay.

Oh, love is a terrible feelin.
It makes ye go weak at the knees.
When intae yer hairt it comes stealin,
Man, ye just want to cuddle an squeeze.
I knew that I couldnae resist her
The first time I glanced at her face,
And the very first time that I kissed her,
Ma hairt nearly fell from its place. CHORUS
