So Long, Farewell Jay! (Video)

Last night, February 6th was Jay Leno's last night as host of the Tonight Show, before Jimmy Fallon takes over. One of the guests was Billy Crystal, who coincidently was one of Jay Leno's guests on his first show.

Crystal sang with a chorus, a take-off of "So Long Farewell" from the Sound of Music, and there were lots of surprise guests including Jack Black, Kim Kardashian, NBA superstar Chris Paul, Cheryl Crowe, the Big Bang's Jim Parsons, Carol Burnett and the one and only Oprah!

It was great! If you missed it, here it is!
