OK...I talked to Kerry today, and together, we figured out what songs have played on the Christmas tree from the start til when it was redesigned. The first two have been pretty much regulars every year, the others added and/or dropped from year to year.
The Carol of the Bells
The Hallelujah Chorus
Joy To The World
Jingle Bells
Ode To Joy
Here We Come A Caroling/God Rest Ye Merry Gentlemen Medley
Christmas Hymn
Do You Hear What I Hear
