This is a slide I found in a book of tunes given to my father by Peg Morley in the 70's. Her brother Daniel Murphy had learned fiddle from Tom Billy Murphy and this was one of the tunes from that book. In the book it's called the slide but I called it the Tureendubh here.
I've included the original notes below as written down by Daniel :)
