Lyrics:

Rory:
I'll have a Blue Christmas without you
I'll be so blue just thinking about you
Decorations of red on a green Christmas tree
Won't be the same, if you're not here with me

Rory with New Directions harmonizing:
And when those blue snowflakes start falling
That's when those blue memories start calling

Rory (New Directions):
You'll be doin' all right, with your Christmas of white
But I'll (I'll have a blue) have a blue, blue blue blue Christmas

Rory with New Directions:
Ah-Uh-uh-uh-uh
Ah-Uh-uh-uh-uh

Rory:
Decorations of red on a green Christmas tree

Rory with New Directions harmonizing:
Won't mean a thing, if you're not here with me

Rory with New Directions harmonizing:
I'll have a Blue Christmas that's certain
And when the blue heartache stops hurting
You'll be doin' all right, with your Christmas of white

Rory (New Directions):
But I'll have a blue blue Christmas
(Uhhhh) Uh-uh-uh-uh
