The Christmas Song by Nat King Cole is one of the classic songs and my favorite song. I love Nat King Cole.
Just so you can rewind and sing along I've searched the lyrics and pasted here. It's the exact lyrics. Who knows you can practice and sing at your school or community's Christmas special performance too!
Chestnuts roasting on an open fire
Jack Frost nipping at your nose
Yuletide carols being sung by a choir
And folks dressed up like eskimos
Everybody knows a turkey and some mistletoe
Help to make the season bright
Tiny tots with their eyes all aglow
Will find it hard to sleep tonight
They know that Santa's on his way
He's loaded lots of toys
And goodies on his sleigh
And every mother's child is gonna spy
To see if reindeer really know how to fly
And so, I'm offering this simple phrase
To kids from one to ninety-two
Although it's been said
Many times, many ways
Merry Christmas to.. You!
