Chris Stapleton had a busy night on Monday (May 8) when he stopped by The Tonight Show to perform a song from his anticipated album From A Room - Vol. 1 and suit up as a member of ZZ Top alongside host Jimmy Fallon and Kevin Bacon for a bit of revisionist history on the bearded rocker's "Legs" for the show's "First Draft" series.

The alternate version of the massive 1983 hit apparently featured much different lyrics the first time around, as evidenced by Fallon (aka Dusty Hill) singing "She's got arms / They're like legs but on her upper half / She's got elbows / She scrubs them when she takes a bath," as Stapleton (aka Billy Gibbons) added: "She's got hands / She knows how to wave them / She's got eyebrows / She knows how to raise them."

For the record, she's also got nostrils, teeth, thumbs, feet and butt cheeks, plus more. Check it out:

Stapleton came back later in the show to get a bit more serious for a run through his soulful country ballad "I Was Wrong."
