There's something that makes traditional Irish songs in general and carols in particular beautifully stand out at the music arena! I've heard Wexford Carol performed live on the harp and was a sight to behold, truly. I wish I could also hear it played by Yo Yo Ma on the cello, that would be huge! As for the this particular arrangement, it has all you might need from an SSA piece. Very well arranged and laid-out. The harmonies and the rhythms are quite fluid, but that's characteristic for the Celtic music in general. The result is beautiful, anyway!
