If you stayed up late to watch NBC's Late Night with Jimmy Fallon last night, you saw Robin Thicke perform a much different version of "Blurred Lines" than you've been hearing all summer.
Robin joined host Jimmy Fallon and his house band, The Roots , to sing his smash hit. What made this rendition so much fun was that everyone was playing elementary school classroom instruments, like a xylophone and cowbell.
This is a recurring bit for Fallon. Mariah Carey and Carly Rae Jepsen are among the previous artists who have performed "classroom instrument" versions of their music on his show.
