I think this is a variant of Merry Harrier’s. A similar version was posted in Ador: https://thesession.org/tunes/3038
Nice tune, like it in E dorian. I know it as a highland pipe tune in A dorian called Cup of Tea (not the wider know Cup of Tea)
Cup of Tea
Ah, I see Merry Harriers is also known as Cup of Tea. Nice variant though.
A very similar tune is in the Gunn Book (Fermanagh 1865) as Margret O’Donnell’s Reel. Also very like the Three Sisters/the Merry Sisters
