Christmas, Christmas time is near
Time for toys and time for cheer

Hurry Christmas, hurry fast
Want a plane that loops the loop
Me, I want a hula hoop
We can hardly stand the wait
Please Christmas, don't be late.

Okay fellas get ready
That was very good, Simon.
-Naturally.
Very good Theodore.
-Ahhh.
Ah, Alvin, you were a little flat, watch it.
Ah, Alvin. Alvin. ALVIN!

Want a plane that loops the loop
I still want a hula hoop
We can hardly stand the wait
Please Christmas, don't be late.
We can hardly stand the wait
Please Christmas, don't be late.

-We want to sing it again!
Now wait a minute, boys
-Why can't we sing it again?
-[chipmunk chatter]
Alvin, cut that out..Theodore, just a minute.
Simon will you cut that out? Boys...


That's pretty much it, there is talking in between verses but you can either 
repeat the intro or just play the E chord rhythmically for a couple bars instead! 
i should have a youtube video that shows how i play it up shortly!
