Jim - I would think that in a way it would be a great satisfaction for a songwriter to have people assume his songs are trad.; it does indicate a (wonderful) kind of success. On the other hand, I don't suppose that puts money in the bank!

I'm scared to ask what other songs you wrote - I might find you wrote my entire repertoire. You're not the litigious type are you? I'm afraid there wasn't much left after the bar bills were paid ...
