“Every time a contract got to be renewed, I would think about it and say, ‘Maybe it’s time,'” the 80-year-old Philbin told Katie Couric during a special edition of ABC’s “20/20” this week. “Because most of the people my age are gone, long gone. And I just thought this was probably a good time to go.” So what’s next for Philbin? He has hinted there may be something else in store, but told Couric, “If nothing comes up, fine, I’ve done it all anyway, believe me.” Several celebrities showed up this week for Philbin’s final farewell: Vice President Joe Biden, David Letterman, Donald Trump, Bret Michaels, Josh Groban, Tony Bennett and former “Live!” co-host Kathie Lee Gifford.
