Here are some of the lyrics:
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 12 o'clock
He'll be coming down the chimney
Coming down the chimney
Coming down the chimney, down!
In doing a search for the lyrics, I cam across this commentary. I'm glad I'm not alone in my feelings of this song.
