There are a lot of bands whose name starts with the word Black. The Black Keys, Black Lips, Black Sabbath, Black Flag, and Black Star are just a few of the more well known acts. The Roots' Questlove and Captain Kirk Douglas perform as Black Simon and Garfunkel from time to time. It's the Simon & Garfunkel acoustic duo, but black. Previous performances have included Daft Punk's "Get Lucky" and the Ke$ha and Pitbull hit "Timber."
It's a short performance, at about one minute, but still hilarious. The harmony singing is completely on point, even though it's a comedy act. Also, they go into the real Simon & Garfunkel's "The Boxer" at the end, with Questlove doing an acoustic snare with gigantic echo. The Roots really are one of the best bands on the planet because they throw stuff like this together so often.
