We know for sure that musicians Sheryl Crow, Will.i.am, Jennifer Hudson, Michael McDonald, and Stevie Wonder will be there jamming out but word around the street says there’s going to be a surprise after Barack Obama’s speech at 10:00 (Eastern Time). Will we see the boss? Maybe he’ll bring Bon Jovi with him? No one knows for sure, we can only guess, everything is all hear/say until tonight. stay tuned people!
