David Letterman on CBS ‘Sunday Morning’, But Not Talking About That

In an interview taped Tuesday, two days before he testified before a Manhattan grand jury in the alleged extortion case involving him, David Letterman sat down with CBS’ Anthony Mason for an interview for “Sunday Morning.”

It’s for a story on Letterman’s sidekick of 27 years Paul Shaffer. Shaffer has a new book coming out. The story airs this Sunday morning.
