I love when Jimmy Fallon & the Roots grab the classroom instruments and perform. This is one their best.

Jimmy, Robin Thicke, and The Roots and some instruments you would find in an elementary school classroom perform in the 'Late Night' music room singing Robin's hit song, 'Blurred Lines.' (instrument list below)

Jimmy Fallon - wood block, Casio keyboard
Robin Thicke - spoons
Questlove - wooden clacker
Mark Kelley - kazoo
Kamal Gray - xylophone
James Poyser - melodica
Captain Kirk - ukulele
Tuba Gooding Jr. - recorder, banana shaker
Frank Knuckles - cowbell
Black Thought -- maraca
