'The Tonight Show' got Madonna to sing 'Holiday' as the Roots played children's instruments

What do you do if you’re Jimmy Fallon and Madonna is your guest? You get her to play “Holiday” on kids' instruments with the Roots, of course.

Fresh off her Meerkat video premiere of “Ghosttown,” Madonna sat down with the festively dressed band on The Tonight Show and played a stripped-down version of her ‘80s hit. She handled vocals and cowbell; the band brought in kazoo, xylophone, melodica, and bongos.

Madonna really brings it at the end with that whistle.
