Piers Morgan Tonight: David Letterman on his first post-9/11 show

Beginning on Tuesday May 29th, “Piers Morgan Tonight” welcomes the return of “Guest Host Week,” and it does so by inviting a pair of icons boasting a combined eight decades of television chops.

With the incomparable Regis Philbin keeping Piers Morgan‘s seat warm, the legendary David Letterman pulls up the guest’s chair, as the two longtime friends fill the hour with candid commentary and engaging exchange.

As the topic turns to more serious matter, Philbin asks Letterman to review his first show following September 11th:

“I remember that night and I remember not wanting to go back, not feeling ready to go back, but knowing we had to go back,” says Letterman. “And, you know, my concerns were minimal compared to people who…really suffered.”
