I used to know this tune years ago. I learned it from a Micho Russell book called “The Piper’s Chair,” which has little tidbits of folklore and such in amongst the music. I worked it up properly today, because I heard it at a session last night and couldn’t quite play along. And a certain Elizabeth Crotty disc has just moved up on my list because I notice it contains this tune played on the concertina—it’s fun to compare the versions I work out with the versions other concertina players do.
