Privately Jon uses his given name John Bongiovi<quoted text>
Not funny at all! Jon & his wife ( Mr. & Mrs. Bongiovi) were there last night "Bon Jovi" is a band it has 3 other men in it. Well maybe only 2 other men now and none of them were there. This is typical and part of the problem with the band "Bon Jovi"
Professionally Jon goes by Jon Bon Jovi
It is not unusual for people to refer to people by their last name, which in this case Jon being there for what he does professionally would be Bon Jovi.
