Wake up with this homeless guy has a nice ring to it, although the piano could use a tune up if we're being honest. Everyone knows he Come Sail Away medley is much easier to appreciate in it's natural C Major. And on subject - C Major is pretty fucking easy. Not trying to diminish his accomplishments but that's like saying Ted Williams was a good hitter because he knew how to run to first base. Both guys can still play just appreciate them for the right reasons.
PS - Update: my guy is crushing it at a hotel lounge, hopefully in something more challenging like A minor
