Here's my transcription, with a couple of gaps, and some other parts uncertain.

THE CAMERONIANS
As sung by Kenneth McKellar on "The Early McKellar, Vol. 2"

[a] Have ye seen the Cameronians?
They're the boys who are the bonny 'uns:
Liltin' laughin' Cameronians,
Bravest o' them a'.
Come and cheer the Cameronians:
Better lads by far than ony 'uns,
Lichtsome, laughin' Cameronians—
None there are sae braw.
From the days of Killiecrankie,
Finer ... and fair and swanky.
Lassies fall wherever they go.
Far-off lands are less ....[?—rhymes with "they go."]
Have ye seen the Cameronians?
Liltin' laughin' Cameronians,
Best and bright and braw and bony 'uns,
Bravest o' them a'.

[b] From the hills of Lanark and the fields along the Clyde
Come a band of soldier boys who fill the heart with pride:
Hamilton and Wishaw, Bothwell and the rest,
Meet the laughing laddies that the lassies love the best.

REPEAT [a].

Liltin' laughin' Cameronians,
Bravest brawest Cameronians,
I love them best of a'.

[Alexander Morrison also sings this song on "Scottish Memories."]
