Everyone who attended yesterday's Wawa Welcome America Concert in Philadelphia was treated to an extra special performance when The Roots, DJ Jazzy Jeff, and Common were sharing the stage. They proceeded to rip through Eric B & Rakim's "Microphone Fiend" before being joined by Queen Latifah.

She performed her classic single "U.N.I.T.Y.," which segued nicely into Com's cover of Notorious BIG's "Juicy." The Queen wasn't done there, though, and proceeded to jam on "Just Another Day" and "Ladies First." But the best part? You can watch it all at your leisure in the above video. Enjoy.
