Collaboartion: Green Day and U2 - The Saints Are Coming

Ignore the depressing images of New Orleans for like, 3 seconds and you can respect what these two bands did (and are doing). While no one wants to be the guy that compares Green Day to U2 (U2 kicks their punk asses), you can't help but hear the different vocal styles. Even the song itself is different styles, sometimes Green Day and others U2. Pretty remarkable.
