Will Fyffe wrote and sang and recorded it. Fyffe was a Dundonian (born in Dundee, other side of Scotland). After a music hall gig one night in Glasgow, in Central Station, he met a jovial drunk, and asked him if he belonged to Glasgow. "Yes, I do," said the drunk, "But tonight I feel that Glasgow belongs to me." Like any good C&W songwriter, Will Fyffe wrote the song and ran with it. Very few Glaswegians sing it.
