I don't see why not. He's better than run of the mill AOR rock bands we've had in the past. Live being a great example. IMO he produces good summertime music, and would get the crowd going. I imagine support won't be of Jon's choosing anyway as it's a festival.

Besides last time Jovi had a great rock band supporting, Biffy Clyro, the majority of fans crucified them for being different from the usual shit radio rock junk.
