NBC said Thursday that George W. Bush, Bill Clinton, Jimmy Carter and George H.W. Bush will gather for the hour long "All Together Now: A Celebration of Service," which will air March 28.
The gala, to be held at the Kennedy Center the week before the special airs, also will spotlight the first President Bush's legacy.
Clinton, who has worked with the elder Bush to raise money for tsunami and hurricane victims, is the honorary co-chair of the event that will include music and celebrities.
President Barack Obama, scheduled to be abroad when the gala is held, will narrate a short film on the history and value of service in the country, NBC said.
