Not only did he just tell Roger Waters to go screw himself, there is also this:
"Some years ago, I was in the office of a straitlaced, middle-aged lady who was in charge of my law firm’s support staff. I noticed a photograph on her desk of herself with a long-haired guy who looked like a rock musician. It seemed incongruous, so I asked about the picture, and she told me this story."
"She and her husband had a boat in a marina on the St. Croix River, which constitutes much of the boundary between Minnesota and Wisconsin. One Saturday afternoon, they were working on the boat, polishing fittings and so on, when a man approached them. “Excuse me,” he said, “would you be interested in renting your boat out for an afternoon next weekend?” They asked what he had in mind, and he explained that he worked for “Jon Bon Jovi, the singer.”
"Bon Jovi was going to play a concert in the Twin Cities the following Saturday night. The man explained that there was a retarded boy in the Twin Cities–sorry, I honestly don’t know the current euphemism–with whom Bon Jovi had a big brother relationship, and whenever he was in Minnesota he made time to spend with the boy. They thought it would be fun to go boating on the St. Croix. So, could Mr. Bon Jovi rent their boat for the following Sunday? Our personnel director and her husband said that they would be happy to lend their boat for free, if they could come along."
"The following Sunday, at a time when most rock stars of that era (or any other) would have been sleeping off a night of excess, Jon Bon Jovi, his assistant and the young boy met with my friend and her husband at the marina, and enjoyed an afternoon of boating on the river. That’s when the photo was taken. There is nothing unique about Minnesota: I assume that for several decades, Bon Jovi has done similar good deeds around the country with zero publicity. So, as you can imagine, I have long had a good opinion of Jon Bon Jovi."
