I love Carol of the Bells too, Gary. It's one of my favorites.
I also love "Sleigh Ride", "Do You Hear What I Hear?" and "O Holy Night".
And I also love Handel's "Hallelujiah Chorus" from The Messiah. I remember playing this every Christmas with my chamber orchestra here in Indianapolis, along with many other songs from The Messiah.
