Mike Vass (composer of Cavers of Kirkcudbright) taught us this tune in Skye in 2017. Having searched for versions, it seems it was an old lullaby, as Ille Bhig means Little Boy.
I want to add it to our list because it’s easy to learn but with a cool edge to it’s rhythm. I’m sorry I haven’t managed to find more links. Perhaps we’ll record ourselves playing it and I’ll add it to this page.
