Comedian Jay Leno has opened up for the the first time since his one-time U.S. TV rival David Letterman announced his departure from The Late Show last week (03Apr14), joking that the two late-night favourites are planning to take on Broadway in their retirement. The former The Tonight Show host gave up his post after 22 years in February (14), and now Letterman is making plans to bow out after 21 years as The Late Show's emcee in 2015. Leno tells Extra that the two are planning to start theatre careers in Neil Simon's play about a bitter Vaudevillian duo, who grow to hate each other after a 40-year career. Leno quips, "He and I are gonna do The Sunshine Boys on Broadway, so we're very excited about that." When asked who he thinks should take over for Letterman, Leno stated, "I don't know a lot of good people out there." The late night TV hosts have been feuding for almost two decades after Leno was chosen as Johnny Carson's successor on The Tonight Show over Letterman, who was then the host of Late Night, a talk show which aired immediately after Carson's weeknight programme.
