There's a video on YouTube of The Corries singing this in their 1980s series for ITV with the combolins in front of a fire and you can ascertain from Roy's singing that the text is essentially the same as Learchilds. The one difference is "wild wind" rather than west or south. I'm not at home at present so can't check The Corries' songbooks (there have been several generations of them since the 1970s) but what I can say is that for most of George Weir's songs, the melodies were actually written by Roy Williamson, so the chances of their words differing somehow from George's original seem slim. It was a writing partnership of sorts that supplied historical sounding texts for The Corries' repertoire (Lord Yester, Weep Ye Weel By Atholl, Arkinholm etc), and I wouldn't put too much store in the accuracy or otherwise of the place names, as other songs would indicate some poetic license being taken for lyrical / singable effect now and again.
