Late last year we saw Chris Cornell perform his track from the Machine Gun Preacher Soundtrack, "The Keeper" live on Kimmel. Last night he made sure we didn't forget his gentle ways with a performance of the same track on Leno. This time Alain Johannes wasn't on hand to lend his guitar skills but the addition of some strings will surely raise a few hairs on your neck. Beautiful.
