The Roots will be house band on Jimmy Fallon's show

Philly hip-hop heroes The Roots will be comedian Jimmy Fallon's house band when his late-night show debuts next summer on NBC, a spokeswoman for Island/Def Jam Music Group confirmed moments ago. Label publicist Adesina Dowers said she was not certain what the slot means for the band's touring and recording capabilities, but she was able to confirm rumors the group will join Fallon next year when he takes over Conan O'Brien's "Late Night" show when O'Brien moves to Jay Leno's "Tonight Show" slot. We told you two weeks ago that Fallon was in town taping something with the Roots at Kung Fu Necktie (1250 N. Front) in Fishtown.
