Richie,
I'll try and get the song translated from Gaelic but what I can hear are just new words by Alasdair Gillies with no similarity to anything posted already. Alasdair was making an attempt at singing in a Country and Western style, trying to 'modernise' Gaelic song to appeal to a wider audience. That was 40 years ago and may not have had any efect then but there is a much wider apreciation of Gaelic now .. see the new TV station Alba on Freesat for example.
