Who originally sang "This Christmas"?

Question

I remember an old version of the song that I loved as a kid and I think he probably was the original singer but I don't know who it was. Here's a sample of the lyrics...
"Hang all the mistletoe, I wanna get to you know you beeetttterr. This Christmas!
And when we trim the tree how much fun it's going to be together.
This Christmas!"

Answer 1

The first person I'd ever heard sing it was Donny Hathaway back in the 70's. Great song!
