This day in music history.

December 23, 1957, Elvis got a haircut.
Blue Christmas
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 dear, if you’re not here with me
And when those blue snowflakes start falling
That’s when those blue memories start calling
You’ll be doin’ all right, with your christmas of white
But I’ll have a blue, blue blue blue christmas
DLAK note: Yup.
