After over 3 decades on late night, David Letterman has 28 episodes left of The Late Show left concluding on May 20th and has made sure the last set of guests is a cavalcade of the show’s most memorable, big names.

Thus far, Letterman has “George Clooney, Robert Downey, Jr., Will Ferrell, Tina Fey, Tom Hanks, Jack Hanna, Scarlett Johansson, Michael Keaton, Steve Martin, Bill Murray, Sarah Jessica Parker, Don Rickles, Julia Roberts, Ray Romano, Paul Rudd, Jerry Seinfeld, Martin Short, Howard Stern, John Travolta, Bruce Willis, Oprah Winfrey, The Avett Brothers and Brandi Carlile, Elvis Costello, Dave Matthews Band, Emmylou Harris, Norah Jones, Mumford and Sons, Ralph Stanley and Amos Lee, and many more names to be announced in the coming weeks.” for his final few weeks at The Late Show.

We wouldn’t be surprised at all if Bill Murray was the final guest as he was Letterman’s very first guest.
