The unlikely songwriter behind this festive tune is Twisted Sister frontman Dee Snider
. The heavy metal vocalist wrote the song under the title "God Bless Us Everyone" as a Christmas gift to his wife, Suzette. Unfortunately, Snider couldn't sing it as it wasn't in his range, so he had some studio musicians record his ditty for Suzette. Producer Ric Wake kept a copy and called Snider four years later to tell him Celine Dion wanted to record the song.
Snider agreed as long as nobody revealed his identity, because he feared Dion would change her mind if she discovered the man behind the tune was a controversial rocker. He recalled to the Talk Is Jericho podcast, "The first thing I said was, 'Does she know who wrote it? Do not tell her Satan wrote a Christmas song! Seriously, dude, just put it on the frigging album.'"
