Help me identify the singer

My wife has an mp3 of a female singer covering the Elvis tune, “Are You Lonesome Tonight?” It’s a little slower than the original, and I think the woman sounds like Norah Jones, but I couldn’t find the song on any of her albums.

Any idea who it might be? Sorry, I’d give you more information if I had it, but that’s all I’ve got to go on.

I think it is Norah Jones. Google references it to her many times. Here is one example.. It look like it is not on any album.
