Remember watching all those classic dance shows on television in the 70's and 80's? Jimmy Fallon and his band The Roots have loaded up the time machine and taken us on a trip back to the days of the dance line. 

Fallon and the Roots do an amazing job of creating an "old school" look with disco ball included, complete with some hidden celebrities in there. See if you can pick them out. You can view the skit in the video above.
