If it helps, I followed Mike Ireland's suggestion. YES, there is a jig! I found this midi of the Gravel Walks jig Written by Cathal McConnell, and this gif of the sheet music. Unfortunately, as Sean said - no chords. (And I play fiddle, so I'm not much help.)

I also learned that Cathal transformed 2 of the 4 parts of the reel into a jig. So if anyone has chords to the reel...
