This video is a few months old, but is just as enjoyable to watch the second time around. Lenny Kravitz was walking through New Orleans and heard some of his music being performed across from Jackson Square. And what does he do when he hears one of his songs being played by a live band?  Well, he joins the band, of course!

Watch as Kravitz first just stands and claps along, and then gets on drums, then takes the mic!!  Incredible!
