Actually they do have a history of appearing or donating to relief effort type things. I imagine if they can work it out they will do something for the hurricane relief effort. Why would you slam them for helping other people or do I just misunderstand you??
As for the touring everywhere it was pretty obvious that jon meant that at some point in their 20 plus year history they have played pretty much everywhere, and that they have been in these places at one time or another.
