Madonna [1] stopped by The Tonight Show Starring Jimmy Fallon on Thursday night, and in addition to performing a song from her latest album, she pulled out an old classic. That's right — Jimmy, Madonna, and The Roots tackled "Holiday" in the latest edition of Classroom Instruments. In addition to the funky sounds, they all donned Hawaiian shirts and wicked-cool shades. We knew their rendition of Meghan Trainor's "All About That Bass" [2] and that epic One Direction holiday sing-along [3] would be tough acts to follow, but the crew really might have outdone themselves this time. Watch the video above.
