It’s by some group called Newsong.

The key lyric…

“Sir I wanna buy these shoes for my Momma please
It’s Christmas Eve and these shoes are just her size
Could you hurry Sir?
Daddy says there’s not much time
You see, she’s been sick for quite a while
And I know these shoes will make her smile
And I want her to look beautiful
If Momma meets Jesus, tonight.”

And of course, there’s a little kid singing the chorus the last time…

You can buy it here if you’re so inspired.

I’m going to go and drink heavily.
