Just a thought (and please excuse me if it's already been mentioned- there are so many posts I may have forgotten seeing it), but would the shows still be going ahead if Jon was the one missing for a dozen shows? Richie and Dave could share the vocals, or they could bring someone in. But would it still be Bon Jovi? Would this forum be split on cancelling the shows, or unanimous in opinion? I know where my money lies on that one...
