Change has come to America Part 2

Okay as I continue to watch the Obama Inaugural Celebration at the Lincoln Memorial, I'm thinking do all these performers in some way express the presidents vision or define him in some artisitc way? Or are these celebrities and performers asked to participate solely for their ability to entertain? Really, is their meaning behind Kal Penn's appearance or is it just "Hey thats the dude who was in Harold and Kumar go to White Castle" and he's a minority? Hhmm, Im growing more skeptical by the moment.
