Ian McCarry a solicitor in Maryhill wrote the song which was later passed off by one of the scottish singers as his own. Ian used to perform it at parties. I don't remember the name of singer who recorded the song as his own but he was sued by Ian & had to pay damages. If you want further info he still has offices at the top of Maryhill rd as well as st George's cross & can give you a copy of the words.
