The Holiday Season is a song by Andy Williams that was originally included as part of a medley called Happy Holiday/The Holiday Season. The song was performed by Mr. Mackey in the Season Twenty-Three finale "Christmas Snow".
It's the holiday season
With the whoop-de-do and hickory dock
And don't forget to hang up your sock
Cause just exactly at twelve o' clock
He'll be coming down the chimney, down
Coming down the chimney, down
