Originally known as Carol of the Drum this song was written in 1941 by Katherine Kennicott Davis. Sometimes you will see this song attributed to C. R. W. Robinson which is a pen name of K. K. Davis.

The Trapp Family Singers (the family that The Sound of Music is based on) popularized the song in the 1950s.

The Little Drummer Boy
Lyrics 

Come they told me, pa rum pum pum pum
A new born King to see, pa rum pum pum pum
Our finest gifts we bring, pa rum pum pum pum
To lay before the King. pa rum pum pum pum
rum pum pum pum
rum pum pum pum

So to honor Him,
pa rum pum pum pum
When we come.

Little Baby, pa rum pum pum pum
I am a poor boy too. pa rum pum pum pum
I have no gift to bring, pa rum pum pum pum
That’s fit to give the King. pa rum pum pum pum
rum pum pum pum
rum pum pum pum

Shall I play for you
pa rum pum pum pum
On my drum?

Mary nodded, pa rum pum pum pum
The ox and lamb kept time, pa rum pum pum pum
I played my drum for Him, pa rum pum pum pum
I played my best for Him. pa rum pum pum pum
rum pum pum pum
rum pum pum pum

Then He smiled at me
pa rum pum pum pum
Me and my drum.

Twelve Days of Christmas
Lyrics

On the twelfth day of Christmas,
my true love gave to me…
12 Drummers Drumming
11 Pipers Piping
10 Lords-a-Leaping
9 Ladies Dancing
8 Maids-a-Milking
7 Swans-a-Swimming
6 Geese-a-Laying
5 Golden Rings (gold rings)
4 Colly Birds
3 French Hens
2 Turtle Doves
And a Partridge in a Pear Tree.

NOTE: Though it is commonly mispronounced and wrongly written today, the 4th day of Christmas is a colly bird. This is an old nickname for a common European blackbird.

Hark! The Herald Angels Sing
Lyrics

Hark the herald angels sing
“Glory to the newborn King!
Peace on earth and mercy mild
God and sinners reconciled”
Joyful, all ye nations rise
Join the triumph of the skies
With the angelic host proclaim:
“Christ is born in Bethlehem”
Hark! The herald angels sing
“Glory to the newborn King!”

Christ by highest heav’n adored
Christ the everlasting Lord!
Late in time behold Him come
Offspring of a Virgin’s womb
Veiled in flesh the Godhead see
Hail the incarnate Deity
Pleased as man with man to dwell
Jesus, our Emmanuel
Hark! The herald angels sing
“Glory to the newborn King!”

Hail the heav’n-born Prince of Peace!
Hail the Son of Righteousness!
Light and life to all He brings
Ris’n with healing in His wings
Mild He lays His glory by
Born that man no more may die
Born to raise the sons of earth
Born to give them second birth
Hark! The herald angels sing
“Glory to the newborn King!”

Joy to the World
Lyrics

Joy to the world! the Lord is come;
Let earth receive her King;
Let every heart prepare him room,
And heaven and nature sing,
And heaven and nature sing,
And heaven, and heaven, and nature sing.

Joy to the world! the Saviour reigns;
Let men their songs employ;
While fields and floods, rocks, hills, and plains
Repeat the sounding joy,
Repeat the sounding joy,
Repeat, repeat the sounding joy.

He rules the world with truth and grace,
And makes the nations prove
The glories of His righteousness,
And wonders of His love,
And wonders of His love,
And wonders, wonders, of His love.

Original third verse:
No more let sins and sorrows grow,
Nor thorns infest the ground;
He comes to make His blessings flow
Far as the curse is found,
Far as the curse is found,
Far as, far as, the curse is found.

NOTES: Although “has come” would seem more appropriate, “is come” is the correct form in the first verse. Grammar Girl wrote about this on her website. Here is the important paragraph, but it is worth checking out the whole article if you are curious about the grammar of the song.

It actually turned out to be a pretty tough question, but I eventually discovered that the phrase the Lord is come uses an archaic form of English that was very common back in 1719 when “Joy to the World” was written by Isaac Watts. A number of references say that this construction uses the word come as an unaccusative intransitive verb (and don’t worry: you don’t need to remember that because it’s a form that’s now nearly extinct in the English language [1]).
