Does anybody know where i could find the classical guitar version of carol of the bells?

Are you looking for the sheet music or a recording?
There is a nice recording on this CD--very pleasant recording overall. One of the guitarists, Tom Poore, seems like a really decent guy--I don't know if he's published his arrangements, but I wouldn't be surprised if he were willing to help you out if you contacted him.
