I wish I knew! I don't know any of the titles that were played last night so I have described my vids as 1,2,3,4,5,6, etc at the moment until I find the titles out.
This is a song by Davey Spillane (originally played on the ulienne pipes) called "Midnight Walker" . Jeff plays a short version hear and does a damn good job of mimicking the sound and the expression.
