Mannheim Steamroller’s ‘Silent Night’ or ‘Rudolf the Red-Nosed Reindeer’.
TSO’s ‘Sarajevo’ is good, too.
I have their Angels album. I never could get a copy of the rock opera that Sarajevo was originally a part of (it wasn't a Christmas album). It was originally recorded by a group named Sabotage, and I believe that it was called "Tears of the Gargoyle". I only remember this because I liked the "prologue" from the liner notes that went with the song.
