Subway Riders Help a Guy Finish His Bon Jovi Song

A video has been making the rounds of a subway rider singing Bon Jovi's "Livin' on a Prayer" at the top of his lungs.  He's wearing earbuds and standing in front of a window, so he has no idea that the rest of the passengers are into it.

And when he stops short of the high notes, they laugh . . . and then one woman finishes the verse.
