"Livin' on a Prayer" has been a staple at wedding receptions since it was released in 1986. Does that mean Jon Bon Jovi is required to sing it if he's in attendance? Hell no!

Some people seem to think so, as you'll see in the video below. Jon is approached by singer Lourdes Valentin while she and her band perform a jazzy version of "Livin' on a Prayer." You can't help but feel bad for the guy, his face and body language shows that's he's uncomfortable with the whole situation.

Like a champ he grabs the mic and belts out the rest of the song. But as quick as the tune ends, the smiles are gone from his face.
