Learned this from Donegal fiddle player Dr. Liz Doherty while studying in Northern Ireland. She said it was a slow march and indeed sounds plaintive and mournful at such a speed. There is a grand youtube video of Alistair Fraser playing it with a cello player and a few Galician friends.
Written by Alasdair, and is connected to another of his compositions:
Independence Trail / Galen’s Arrival
Galen’s Arrival refers to the birth of my son, who arrived hours after his mother and I took a long walk on Independence Trail, along the beautiful South Yuba River in California.
Cheers for the extra info on the tune/tunes.
