Bruce Springsteen wrapped up his week on Late Night with Jimmy Fallon by joining the host, disguised as Neil Young, for a cover of LMFAO's "Sexy and I Know It." As the sole guest on last night's third anniversary show, Springsteen also sat down with Fallon for a two-part interview and played a set of his own songs, including "Death to My Hometown" and "Jack of All Trades," from the new album Wrecking Ball, as well as "The E Street Shuffle."

Springsteen had dueted with Fallon's Neil Young impersonation before, on their November 2010 cover of Willow Smith's "Whip My Hair."
