Good point, Starship. I guess NP doesn't have any instruments at all. I remember that bag pipes weren't a very prominent part of the actual instrumentation in this song, even though they are a feature of the story.

I hate to admit it but it's even possible that there were no actual bagpipes in the recording and I just imagined that.

I also posted about this on reddit and there are some people trying to figure it out there too: https://www.reddit.com/r/folk/comments/get3ow/does_anyone_else_know_this_wonderful_song/
