Jon Bon Jovi... Wedding Singer?

So this happened. Jon Bon Jovi was coerced to sing at a wedding recently. He was a guest and presumably just wanted to be left alone. 

Things didn't go as planned. 

The wedding band did a cover of "Livin' On a Prayer." As you'll soon find out, the band is out of tune and the tempo is weird, but Jon got up and sang anyway. Poor guy looks... pissed.
