I think it would be naive to think the band has no say in ticket prices. I also doubt that Jon and the boys sit around saying " We need more money, let's overcharge our fans for a couple shows" I think it has more to do with corporate sponsors, managers, venues, merchandisers, unions, Ticketmaster, etc all trying to get their piece of the pie. With a band like Bon Jovi most of these people see their chance to latch on and get paid. Like Jon said in a recent interview, they call it the "Music Buisiness" and it's not because of the music.
