Song played over the ending credits?

I watched the film on DVD tonight and I was listening to the song during the end credits and wondering who the hell it was, the voice sounded really familiar. I was shocked to see at the end of the credits "Steal a Mule" (written by rice/ferguson) preformed by Damien Rice, Joel something and Amy Ferguson (you said it wasn't credited -this may have been an addition for the DVD). i am a huge damien rice fan and didn't know that he was on the soundtrack... however his websites don't mention anything about this and i don't think it'll be released, unless they realease "Mickeybo & Me" the soundtrack, which doesn't seem likely. I might be able to record it off the DVD, I could send you a copy, let me know if your interested.
