It's a good idea. Everyone's expecting Jackson to simply be more of a nut, and all the media probably want him to fall flat on his face.

If he actually CAN still sing, it would be a pretty phenomenal show.

On a side note, Chris Cornell did an acoustic cover of Billie Jean, and it was freaking awesome!
