Stephen Colbert with The Roots, Jimmy Fallon and Taylor Hicks - Friday

One of the most epic combo in Late Night Show this year sings Rebecca Black's "Friday". All of 'em, from the Auto tunes, black dude in a car, etc. Quiet surprising to see the legendary Roots crew including Questlove himself to performed such song. Another surprise is the former American Idol, Taylor Hicks (Rarely seen on TV though he won the American Idol title on season 5). And, see how Stephen Colbert's face looked so serious when he performed this song. He must be digging the song. Well, Check it out below!

Last Monday, Colbert appeared on Fallon's 'Late Night' to discuss the $26,000 donation he had promised Fallon would donate to DonorsChoose.org without Fallon's discretion. After some comical dialogue between the two, Fallon promised his audience that if they helped him raise the money by this past Friday, Colbert would come back on the show and sing "one of the most important songs of our time." Low and behold, the $26,000 was raised in under 36 hours and Colbert owned up to the promise Fallon made on his behalf.

With support from The Roots, former American Idol winner Taylor Hicks and Fallon himself, here is Colbert's performance of everyone's favorite song of the moment: "Friday" by Rebecca Black.
