Last night, I linked you to a video of some of David Letterman's first morning show. A number of folks have written to me to suggest that at this point in the video, one sees Bill Maher and maybe Larry Miller in the audience. Also, there's a sign in the audience that says "The David Letterman Show" and the person seated just above the "The" looks like Budd Friedman, owner-operator of The Improv. You make the call.
