its going to be great for the idiots saying chris brown should b on stage u guys do realize that earth song is purely about vocal skills and has nothing to do with dancing so why would chris brown make this a better tribute he's not a vocal master piece they have gotten the right ppl michael really loved carrie underwood that's why she was picked if u really dont know who she is then u have some issue thhat need to be taken care of she's very very talented and obviously celine dion is CELINE DION and JHUD is just enough said and everyone knew usher would b a part of this and smokey idk y he's there but why not its going to b great o and noone cares if u guys dont know or care for the grammy's or that song its not for u its to honor him he was passionate about the earth so it only seems right that they do this song though i'd love for them to get everyone together to do we are the world or man in the mirror
