For my entire life (the part I remember at least), David Letterman has been being 'The Late Show' desk. Letterman will put a bow on his 30-year run as a late-night TV show host next Wednesday, May 20th.

Even if watching Letterman is not part of your evening routine, I would encourage you to stay up a little later than usual or put anything else your watching on hold to tune in as a legend comes down the homestretch of an amazing career.

Tonight, Letterman welcomes Julia Roberts, Paul Schafer (yes, he will have his band leader in one of the chairs) and Ryan Adams.
