Well, there are certainly some bizarre moments in that transcription! I don't think I've heard the MacColl recording, but it looks very much like the set in John Ord's Bothy Songs and Ballads (1930; reprinted 1995), with the final verse omitted. There are also several sets in the Greig-Duncan Collection (volume 3, which I haven't seen yet), but I don't know how close they are; likely they didn't vary a great deal. Probably any of those could have been MacColl's source; there was also a BBC field recording made in 1950. It's just a slice of life; no political sub-text.

OH CHARLIE, O CHARLIE

O Charlie, O Charlie, come owre frae Pitgair,
And I'll gie ye out all your orders,
For I maun awa to yon high Hielan' hills,
For a while to leave the bonnie Buchan borders.

O Charlie, O Charlie, tak' notice what I say,
And put every man to his station,
For I'm gaun awa to yon high Hielan' hills,
For to view a' the pairts o' the nation.

Tae the loosin' ye'll put Shaw, ye'll put Sandison to ca',
To the colin ye'll put auld Andrew Kindness.
Ye'll gar Colliehill aye feed the thrashin' mill,
An' see that he dee't wi' great fineness.

To the gatherin' o' the hay, ye'll put little Isa Gray,
And wi' her ye'll put her cousin Peggy;
And in aneath the bands, its there ye'll put your hands,
And ye'll see that they dee't richt tidy.

As for you, Willy Burr, ye'll carry on the stir,
And ye'll keep a' the lasses a-hyowin',
And beware o' Shaw and Jeck, or they'll play you a trick,
And set a' your merry maids a-mowin'.

And for you, Annie Scott, ye'll put on the muckle pot
And ye'll mak' milk pottage a-plenty,
For yon hungry brosers that's comin' frae Pitgair,
And they're keepit aye sae bare scanty.

O Charlie, O Charlie, sae early's you'll rise,
And see a' my merry men yokin';
And you, Missy Pope, ye'll sit in the parlour neuk
And keep a' my merry men frae smokin'.

From John Ord's Bothy Songs and Ballads (1930; reprinted 1995). Ord didn't say where he got the song, but he did print a tune for it. A midi can be heard, until it gets to Mudcat Midis, via the South Riding Folk Network site:
