Look, even if you're not thrilled with everyone that's going to help make this record, remember they're doing it for free and for a good cause. It's going to be a group effort and Brown has said that none of the money will be taxed, so the UK won't make a dime from this, it's ALL going to help the starving and helpless people of Haiti. It's going to cost less than you'd pay for a nice lunch, so stop worrying about meaningless things like whose voice you like or don't like. Give them credit for helping, and join them for a good cause.
