Everyone's wondering how Steven Tyler will do as a new judge on Season 10 of American Idol. But for any of you doubting whether the dude can still rock, take a look at the video for his recent performance at the Kennedy Center Honors.

Tyler was on hand to serenade honoree Paul McCartney by singing a medley from the Beatles' classic album Abbey Road. And Tyler's performance is an absolute stunner! The black tie soiree instantly turned into a seat-dancing rock concert, and even Sir Paul himself was visibly moved at one point. The clip is a great preview of Hollywood Week on Idol, when contestants will be singing in the Beatle-themed Cirque du Soleil show Love.
