Chris Stapleton, Kevin Bacon Rewrite ZZ Top's 'Legs' on 'Fallon'

In the latest installment of the show's "First Drafts of Rock" segment, the guys recall the Top's early version of "Legs" – from their diamond-selling 1983 LP Eliminator – originally titled, uh, "Neck." Stapleton plays the role of guitarist Billy Gibbons, while Fallon is bassist Dusty Hill and fellow Monday night guest Bacon uncannily resembles drummer Frank Beard. The trio feel their way through a parodied version of the song, continually confusing parts of the human anatomy and never quite hitting on those lower bipedal appendages that made the song famous. The Kentucky native plays a good straight man as Bacon's Beard struggles to figure out what he's supposed to be singing about, but Stapleton makes it look easy, doing a particularly good job of pulling off that tricky white-fur guitar look.
