Carnahan learned the song from Gaughan, and 'translated much of the Scots idiom into more standard English' (his words). There may be some slight mishearings in Michael's transcription: Bantry ought to be Banchory, for example.

For Gaughan's transcription from his own singing and some comments on source and modifications, see  http://www.dickgaughan.co.uk/songs/texts/glenlogi.html
