I'd heard it (ie, the way it came to my ears was) as the "Rutherglen". I've no idea about the geography of Glasgow, but it sounded as though it might be a place, which Kelvin Ha' apparently is.This is the oral tradition, as misheard from recordings. I'm not sure whether I really want to know what it "really" is or not after all these years!!
