What better way to say goodbye to Jay Leno  than with the musical stylings of some of Hollywood's biggest stars? On Thursday night, Kim Kardashian , Jack Black , and Oprah Winfrey  (yes — Oprah!) bravely flexed their vocal skills when they sang a spoof version of "So Long, Farewell" to Jay on his final show for The Tonight Show. The stars were introduced by Billy Crystal and were given backup by the "Shut Your Von Trapp Family Singers." Jack, the first singer, poked fun at the fact that this is actually Jay's second time saying goodbye, singing, "If Fallon tanks, you'll be back next year." Meanwhile, Kim cooed, "I told my folks now I won't be the butt of Leno's jokes." Other guests included The Big Bang Theory's Jim Parsons, Sheryl Crow , and Carol Burnett. Watch the video above for the whole musical number!
If the musical number sounds familiar, that's because Billy also broke out a special song when Jay first bid goodbye to The Tonight Show in 2009. Watch a clip of Billy's old number below.
