STAGE TUBE: Colbert Covers Rebecca Black's 'Friday'!

Stephen Colbert, who will next be seen in New York Philharmonic (April 7-9), stopped by The Jimmy Fallon Show to keep his word on a bargain he made with his fellow television host: in return for Fallon raising raise $26,000 for DonorsChoose.org, Colbert would perform the viral hit 'Friday'.  

Among those joining Colbert in Company for the New York Philharmonic will be Patti LuPone as Joanne, Anika Noni Rose as Marta, Martha Plimpton as Sarah, Jim Walton as Larry and Neil Patrick Harris as Robert.

'Friday', from teen singer Rebecca Black, became an overnight sensation - and late-night punchline - when the song was released on YouTube and later iTunes. View Colbert and Fallon performing the song below!
