WATCH: Madonna Sings ‘Holiday’ with Classroom Instruments

In the ways of just about every other contemporary pop artist who appears on Jimmy Fallon's show, Madonna sat down with the Tonight Show host and The Roots to sing one of her classics - "Holiday." She was accompanied by a harmonica, woodblock, some plastic clappy hands, and just about any other instrument you could find digging through the box in the corner of an elementary school music classroom. The result was obviously amazing because, well, it's Madonna.
