Pastor Brian has written about various Christmas songs over the years. Here is a full list of the songs that have been examined:

Angels From the Realms of Glory
Angels We Have Heard on High
Away in a Manager
The First Noel
Come Thou Long Expected Jesus
Go, Tell It on the Mountain
God Rest You Merry Gentlemen
Hark the Herald Angels Sing
It Came Upon a Midnight Clear
Joy to the World
Mary Did You Know?
O Come All Ye Faithful
O Come O Come Emmanuel
O Little Town of Bethlehem
O Holy Night
Once in Royal David’s City
Silent Night
The Twelve Days of Christmas
We Three Kings
What Child is This?
Who Is He in Yonder Stall
