Two of David Letterman’s Greatest Fans Have Their Own Talk Shows

So we’re getting ready for the final show with some reflections.

Tonight on Prime News @ 7, we’ll meet one of Letterman’s first staffers who now is retired in Hixson.

Plus John Mercer shows us the time he got on the air of The Late Show.

CNN airs a special report: "David Letterman says Good Night" at 9 p.m. ET, hosted by CNN’s Jake Tapper.

Here is a clip from that show on two of Letterman’s biggest fans, talk show hosts Jimmy Kimmel and Conan O’Brien.
