I started to learn this years ago, when I sang with a small Gaelic choir (and no, I cannot speak this beautiful language of my ancestors). Back then, I had intended to sing it 'a capella', but I dug the words out again the other day, listened to it again...and decided to give a guitar arrangement a go. I'm rather pleased with how it turned out (7 months into learning how to play, so it's very simple), now I just need to practice it a lot, and remember all the words. Perhaps one day I'll be able to record it and post it on my blog (when it's had a LOT of practice!), but in the meantime, here's the gorgeous version of it by the wonderful Capercaillie.
