"Chestnuts Roasting on an Open Fire" by New Kids On The Block

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 1 to 92
Although it's been said many times, many ways: merry
christmas to you.
