I just spoke to an old Bankie friend, who lives in Dickens Avenue, Parkhall. His family, including many old Singer hands,go back three generations in Clydebank and know every street in the town and has never heard of Cartney's Brae.

The songwriter may have been looking from a high vantage point on Kilbowie Hill across the Clyde to the Renfrewshire Hills, Gleniffer Braes, etc. I've checked the OS map for that area and it's not there either.
