If anyone has the “Live from North Hero” CD (2004 Pipers Gathering), there’s a jig played by Debbie Quigley called the Sports of Multyfarnham (track 9, preceeded by Maid at the Well). In the 2nd part of the jig, Debbie ornaments a 2nd Octave E (4th bar).
I think she’s playing a ghost D just prior to the E and I suspect that she’s also playing off the knee.
Can someone (who has the CD, obviously) please have a listen to it and let me know if I’m right or wrong?
