Oprah, Jack Black and Kim serenade a tearful Jay Leno with Sound of Music’s So Long, Farewell as stars line up to say their goodbyes to TV host on his last episode of The Tonight Show after 22 years. Except for Conan O’Brien’s brief tenure from 2009-2010, Leno had been the Tonight Show host since 1992. Jimmy Fallon’s first Tonight Show will air February 17. Wish them the both best of luck!
