File1:

Chestnuts roasting on an open fire
Jack Frost nipping at your nose, yeah
Yuletide carlos 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 loading lots of toys and many goodies on his sleigh
And every mother's child is gonna spy
To see if reinderr really know how to fly, yeah, yeah

They know that Santa's on his way
He's loading lots of toys and many goodies on his sleigh
And every mother's child is gonna spy
To see if reindeer really know how to fly
And so, Im offering this simple phrase
To kids from one to ninety-two
ALthough it's been said many times, many ways
Merry Christmas to you
Yeah and so, Im offering this simple phrase, oh woah
To kids from one to ninety-two, yeah yeah
Although it has been said, many times, many ways
Merry Christmas, Merry Christmas, Merry Christmas oh no,
Merry Christmas to you

File3:

It's the most beautiful time of the year
Lights fill the streets, spreading so much cheer
I should be playing in the winter snow
But I'ma be under the mistletoe
I don't wanna miss out on the holiday
But I can't stop staring at your face
I should be playing in the winter snow
But I'ma be under the mistletoe
Everyone's gathering around the fire
Chestnuts roasting like a hot July
I should be chilling with my folks, I know
But I'ma be under the mistletoe
