I'm sorry I started this latest discussion as I didn't know it had been thoroughly researched earlier. I was born just around the corner from Tannahill's cottage in Paisley and our tenement building faced the graveyard where he is buried. We used to hide there after stealing apples from the Minister's garden! My mother was Paisley born and bred and used to sing Thou Bonnie Wood of Craigielea often. I first noticed the connection with Waltzing Matilda over 50 years ago as they both share obvious passages in verse and chorus. Waltzing Matilda is an original tune in its own right but your ears have to be painted on if you can't hear the similarities with Carigielea.
