I love when we get a chance to see a big celebrity let their hair down and have some fun. I also like how late night talk shows have gotten a lot more informal (I don't think we'd ever see Johnny Carson do something like this). So, Madonna joined Jimmy Fallon, along with his band, The Roots, with a bunch of classroom instruments (a toy xylophone, cheap whistle, etc), and they rocked out to her classic "Holiday". Watch:
