Watch Will Smith And DJ Jazzy Jeff Perform 'Summertime' Like It's 1991

Drums please!

While it’s been 23 years since '90s hip-hop fans first heard those fateful first two words from DJ Jazzy Jeff & The Fresh Prince’s “Summertime,” the Grammy Award-winning classic is still an all-time favorite.

So when Will Smith, who was on hand at the Palms Casino Resort Friday to support longtime collaborator Jeff and his eldest son Trey (DJ AcE), decided to take his shirt off and get Jiggy with it, the pool partygoers were more than happy to chant, "summer, summer, summertime."

“It’s been a minute since I saw you,” Smith told Jeff. “When was the last time I saw you? We ain’t been onstage in forever.”

Thankfully, some things never change. The legendary duo from Philly rocked the crowd just like they did before Smith became one of Hollywood's biggest stars.
