Off the subject of Roddy McCorley, but since MacPherson has also been mentioned in this thread, with some suggestion that he was not a fiddler, I will. I remember seeing in the National Geographic several years ago, a picture of a broken fiddle supposedly MacPherson's. The caption said it was in a (or the) MacPherson museum in Scotland. I don't remember the date but if I come across it in my collection of Geographics, I'll post that information.
