David Letterman is wrapping up his storied run as a late-night host next week, an occasion that is too big to be contained in a single farewell event. Instead, Letterman and CBS are going to do three nights of big-name guests, a special musical performance, and (most likely) some heartfelt messages of appreciation. The goodbyes will start on Monday, May 18, with Tom Hanks doing his lovable Tom Hanks-y thing and Eddie Vedder (of Eddie Vedder And The Pearl Jams) sitting in with Paul Shaffer and the CBS Orchestra for some kind of special performance. According to The Wrap, this will be Hanks’ 60th time guesting on one of Letterman’s shows (going back to Late Night in the ’80s).
