Late Night with the Roots Featuring Jimmy Fallon

Right now, Late Night with Jimmy Fallon has the rockingest theme song on TV (the Roots' sped-up version of their own 2006 tune "Here I Come," the complete opposite of The Jay Leno Show's lame opening theme, which Vulture amusingly slammed as "a rejected demo from the Beverly Hills 90210 sessions"), as well as the illest late night band (the Philly collective is one of the few bands whose albums I always buy). The Roots always pick the cleverest and most playful walk-on music for Fallon's guests, from Jay-Z's "Lost One" for Lost's Jorge Garcia to Quiet Riot's "Bang Your Head" for head-butting gossip column favorite Kiefer Sutherland. (The Late Night blog keeps track of the walk-on music, easily my favorite part of Fallon's show.) Last night, the Roots awesomely welcomed Dennis Quaid with the Lalo Schifrin theme from Quaid's 1981 movie Caveman. ?uestlove, Black Thought and their cohorts have officially outed themselves as film score geeks.
