Carrie Underwood, Reba McEntire, Brad Paisley, Garth Brooks and Darius Rucker were onstage Monday (March 21) at Kennedy Center in Washington, D.C., to pay tribute to former President George H.W. Bush and celebrate the role voluntary service can play in overcoming the challenges faced by communities. Kid Rock, Sam Moore and Cee Lo Green also performed during the event that was billed as “All Together Now — A Celebration of Service.” Portions of the event will air Monday (March 28) on NBC. In addition to George H.W. Bush, the program was also attended by former presidents Jimmy Carter, Bill Clinton and George W. Bush and ambassador Ichiro Fujisaki of Japan.
