http://en.wikipedia.org/wiki/Celtic_Woman http://www.youtube.com/watch?v=sfO6JpR5Ip8&NR=1 Stumbled across them on my ipod a while ago. I thought I'd share one of my favorite songs (awesome percussion near the end).
Can't say I'm a huge fan of them (my dad is though), but I usually listen to their New Years special cause they're definitely talented.
One of my favorite vocal groups of all time. Defiantly worth listening to when your down. My favorite song from then is Last Rose of The Summer.
