Here's confirmation on Hillary's appearance. Mike Huckabee will get a boost with Leno's show.
Will Huckabee perform tonight with his electric guitar, like clinton did with his sax on the ARsenio Hall show?
UDPATE: Huck plays "pride and joy" with Mama's Kicks
Schedule alert: I believe David Letterman has a new home and schedule: ETC, 11pm tonight. Leno will be on JACK TV, 10pm too.
UPDATE: Huckabee jams with Tonight Show band.
The reviews are in.
UPDATE: David Letterman and Conan O'Brien are BACK (w/ Beards!)
