Steven Colbert Does It Again

Last year, Steven Colbert and the Nation came to the rescue of US Speedskating.  This year, Jimmy Fallon had a challenge bet with him to raise funds for another group. If Fallon raised it, Colbert would appear on the Jimmy Fallon Show to sing "Friday".  Both delivered.  Here's the clip from the April Fools' Day episode of the Jimmy Fallon Show.  sorry about the short commercial in there!
 Enjoy!
