Will Smith and DJ Jazzy Jeff Perform ‘Summertime’ + ‘Jump On It’ [VIDEOS]

Just another reason going to Vegas is awesome. You might get the chance to see Will Smith and DJ Jazzy Jeff perform together.

Jazzy Jeff was performing at the Palms when Will Smith happened to jump on stage and give the audience a pretty amazing, and partially shirtless, performance.

Will and Jazzy Jeff performed "Summertime" and "Jump On It." I'm only a little nervous that the freshly 21 Vegas goers didn't appreciate what they were seeing.
