Fan Dances and Sings to Bon Jovi Song at Ball Game

If you've ever been to a professional Basketball game, you know that they have lots of entertainment during time outs, and at other breaks in the game.  One fan took it upon himself to entertain other Boston Celtics fans.  It looked like the camera was just showing the audience while playing Bon Jovi's "Living on a Prayer".  They just happen to catch a dude who really loves that song.  When he noticed he was on camera, he went for it.
