Later, Shaffer expresses gratitude for the success of "Late Show with David Letterman" run and reveals why he'll be a guest on the show tomorrow night.

Explains Shaffer, "I made a rock video...and I redid the tune "On Broadway" because I just felt like this is my story. I started on Broadway in 1984...now my name is actually in lights...so that record is sort of my story. I'm going to show it tomorrow night."
