Published by Sandy Shalk (A0.948741). This is a wonderful, minor-key O'Carolan tune. This arrangement of Mabel Kelly is in the key of D minor in Open G tuning. There is a lovely version by harpist Allie Robertson whose rendition I found to be very inspiring. This one is for lovers of Open G tuned guitar!
