Hmmm... could that be because you don't really hear interviews with the rest of the band that often? Use a little common sense here. Jon is the one the media focuses on so, of course, you'll hear of his perspective on a given topic more often than you'll hear from the other guys. They did it to keep Jon happy, huh? I suppose you were a fly on the wall when Jon went into dictator mode and demanded the other guys perform at the Concert for New York.

You don't think as natives of the area, they wanted to do something for their neighbors? Almost everyone with a heart in this country and around the world wanted to do SOMETHING to help whether it was donate money or give blood or make a trip to area to adopt animals left lost and homeless or just to say a prayer. The band could do something through music and they did it. They probably did a lot we'll never know about as well.
