There's no denying that The Roots are are the greatest band in Late Night. We've had a ton of guests on the show, and The Roots always make it a point to come up with a unique song for each guests and give them a little love. In return a ton of guests noticed the songs and gave The Roots some love right back. In honor of our 500th show, we cut together every one of those guests showing The Roots love. Enjoy.
