skipper, if it is a "new" tune, your best bet might be to xerox the MS that you have, and send it (snail or gif e mail) to someone who reads music, and let them make you a tape or MIDI from it. If it's like most "Celtic" style stuff, he plays ornaments that are not in the score, and you will prob'ly need to figure those out for yourself.
