There was a viral video last fall of a man on a subway singing Bon Jovi's "Livin' on a Prayer" at the top of his lungs. The other passengers laughed at him and a couple even sang along. He's back again and this time at a crowded park on a bench singing the same tune. The Bon Jovi fan gets better results this time around. After about twenty seconds of him singing alone everyone in the park within ear shot belts out the chorus with him.
