Song name

I know there’s plenty of threads like this on here and I’ve googled extensively to try to avoid making another but I haven’t been able to find the song ;o I’m sure someone will have heard it as I know that I have, it’s used in a film I’m pretty certain (I had a feeling it was either the Fall or The Assassination of Jesse James, but a quick skip through each soundtrack didn’t help), and any assistance in naming it would be greatly appreciated. Thanks. (http://www.youtube.com/watch?v=ksjVcYqntiQ)
