GARTH BROOKS wasn't the only person who sang for JAY LENO'S final "Tonight Show" last night.  KIM KARDASHIAN sang for him, too.  Thankfully, it was only for one verse.


Kim was part of an ensemble that sang a specially-tweaked version of "So Long, Farewell" from "The Sound of Music".  Her line was, quote, "So long, farewell, tonight I told my folks. And now, I won't be the butt of Leno's jokes."


Billy CrystalJack BlackCarol BurnettJim ParsonsSheryl Crow and Oprah Winfrey all showed up to add verses, too.
