The Kennedy Center in Washington, D.C. hosted four former presidents at a gala event Monday night to honor former President George Herbert Walker Bush.

Three other former presidents including Jimmy Carter, Bill Clinton and George W. Bush were in attendance to celebrate the elder Bush's years of service to America. It was the first time the four living former presidents had been together since President Barack Obama's inauguration two years ago.

The evening was a tribute to the elder Bush, who issued a call for service at his inauguration and described people and organizations that help others as "points of light."

Country music recording artists Carrie Underwood and Garth Brooks along with Sheryl Crow, Reba McEntire, Kid Rock, Darius Rucker, and others performed at the event.

"It's the whole volunteering thing. That's why we're all here is for each other, and 41 understands that," Brooks said of the elder Bush.

"It's great that they're honoring him, because that's the only way we're going to get anywhere is together. He recognizes that, and I think that's cool," he added.

NBC taped the celebration and will broadcast the event on March 28. Check local listings.
