This is the version sung by Cilla Fisher & Artie Trezise on their album 'Balcanquhal'. Maybe it'll save Ewan some work.

Chorus:
Singing, hey Donal', ho Donal'
Durrum a do a day

As I come o'er sweet Martin Braes what do you think I seen
A braw young piper laddie come a-linking o'er the green

He played a reel and he played a jig and he played a sweet strathspey
He roosed ma hairt till its beats kept time tae the tapping o' ma tae

Well I've nae gown tae offer ye, I hae but little gear
But we'll hae love and freedom gin you follow me, my dear

There's gowd on the broom o' the Sidlaw Hills, honey ben the heather sweet
There's a speckled crow in the (?)

Syne he blew up his chanter and sic a spring he plays
So I chose love and freedom tae wander a' the days
