I learned this tune from my teacher. It’s composed by Mick McAuley and appears on the Solas album The Words that Remain. I’ve also heard it on Emily Smith’s album A Different Life. It’s a great set ending tune and can be really pushed along.
Great for trying out those open string roles on the fiddle but it’s also got a high C in it, so needs a position change (unless you have huge hands). I find it best to change to 2nd position in the 6th bar of the B-part, when you hit that high A, then slip back into 1st on the open E in the following bar.
