This may be my FAVORITE version of this song ever! Aerosmith performed on The Tonight Show with Jimmy Fallon last month -- and they recorded something special before they left the show's studios.
The band, Jimmy Fallon and The Roots did a version of "Walk This Way" on classroom instruments. It's a bit that Fallon has done with numerous musical guests over the past few years. The show posted the entire performance on YouTube Wednesday afternoon ahead of its airing on that night's episode.
