I should also have added the following for Brochan Lom.

From Dingwall in the 1940s,

Oh, the black bull's broken oot and buggerit aa the kye x3 He och oh och ee och oh och ee och oh och aye

From I think Greig Duncan, so Aberdeenshire turn of the century :
The black bull's broken oot an eaten aa the corn
Ah canny wait till Saturday, so I'll away the morn

From my own making for a song project in Paisley
Broken lum, tummled lum, broken lum in New Street x4
Broken, tummled, tummled, tummmled, broken lum in New St etc

From a TV documentary some 8 years ago on music in the North of Scotland
Broken down, broken down, broken down in Beauly x3
Tow me back, tow me back, tow me back to Dingwall

The notion that all or most references to Charlie in song are about BPC is a pleasant romantic notion. For example, his lack of ability in hoeing corn is omitted by most of the accounts of the '45 Rising, is it not? We are of course on surer ground when we contemplate him looking up the legs of drawers.
