Homeless Man Walks Up To A Piano, Stuns Passerby With A Flawless Performance

Earlier this week a facebook user uploaded this video of a homeless man playing a 'public piano'.

The song is an acoustic version of Styx's "Come Sail Away." The video has blown up with 100,000 likes overnight and has been seen by more than 4 million people.

The man featured in the video has been offered the chance to audition for a potential act at a local piano bar.
