Yes it does but events like these raise alot of money that ends up being used for relief efforts. Everyone does or should do what they can. BJ are entertainers, they join a relief concert, raise awareness and a butt load of cash, usually make personal contributions. Jon and Richie can't go join the cleanup crew, or go work the food line, because that would be more of a distaction than a help, having them there. so they do what they can. I just don't see what is wrong or embarrassing about this.
I work for a company that along with retail restaurant outlets, also grows wheat and the other grains we use in our products. Tomorrow, we are all spending 12 hours baking bread etc... that's going to get shipped to Loiusiana and Mississippi for hurricane relief supplies. This is what we can do so we are.
