This interpretation is CAH-RAY-ZEE! I actually worked with the conductor, Greg Beardsell, with my choir in Ireland, and I wonder if that's how he discovered the song (we were singing it when he came to help us out). He's a super great guy with a real knack for feeling music.
And that bodhrán player? Thanks for making me feel totally inadequate, buddy!
Enjoy, and thank our lucky stars Abby's not having us sing it at that tempo!
