Hi Susan, Please don't confuse me with that other dan.("such a thing as books".....what a jackass.)It looks like Helen has given you the same sources that I would have for this tune. But if you dont have software to read MIDIs and convert them to tab you will have a problem. My personal favorite is "noteworthy composer." It is available for PC users at the ZDnet shareware archives.

The Chieftains have a great version of this tune on "the Long Black Veil" sung by Sinead O'Connor. But for a really unique version check out The tune "Sad Wedding Day" on Ashley MacIsaac's CD "Hi, how Are You Today."
if I can help with anything else , let me know Dan Mulligan
