Many found out Letterman was ending his show just moments before he taped his big announcement
Just before David Letterman took to the stage to make his retirement announcement, his director shared the news with the staff, leaving them stunned and emotional.
“Some people were teary. Many people didn’t know it ahead of time,” a source tells PEOPLE. “People are really in shock. People can’t believe it. We always thought it was gonna happen – just like that.”
“Johnny Depp was there and he told Dave, ‘You have some weepers back there.’ Some people were upset.”
But they were also rooting for their boss, who marked three decades on air and announced his exit with gratitude and his trademark humor.
“I just want to reiterate my thanks for the support from the network, all of the people who have worked here, all of the people in the theater, all the people on the staff, everybody at home, thank you very much,” he told stunned viewers. “We don’t have the timetable for this precisely down – I think it will be at least a year or so, but sometime in the not too distant future, 2015 for the love of God.”
Said the source: “It was sad but also sweet and honorable the way he did. Everyone there wants the best for Dave.”
