As you may know, before David Letterman started his late night show (called Late Night) on NBC, he briefly had a daily morning show on that network. It went on the air on June 23, 1980 as a ninety-minute program, was cut to an hour as of August 4th, then left the air completely as of October 24. They then kept Letterman under contract — for a reported $20,000 week — until they could find a new spot for him…which more than a year later turned out to be following Johnny Carson's show.
Here from February 1, 1982 is the first segment in Dave's morning show which I remember as being a rather awkward series that didn't seem certain what it was or why it was on, especially in that time slot…
