Name this song!

So, I saw a post about this song which I've never heard before... somewhat surprising, to be honest. But it is what it is. There was a question about how to play the intro, so I listened... and this is what I came up with...

Anyone know what it is just from this intro snippet? Am I the only one that has never heard it?

Nope... It's the intro to the acoustic demo version of a song by a very well-known artist. Yet, as I said, I'd never heard the song (in any version).
