All five of America’s living former presidents took the stage on Saturday at a benefit concert in Texas to raise money for victims of the hurricane-ravaged southern United States and Caribbean.

Former presidents Barack Obama, George W. Bush, Bill Clinton, George H.W. Bush and Jimmy Carter appeared together onstage at Texas A&M, praising Americans for their willingness to help fellow citizens and urging them to do more.

The effort by the three Democrats and two Republicans has raised over $31 million from 80,000 donors for the victims of hurricanes Harvey, Irma and Maria, George H.W. Bush’s office said.

“All of us on this stage here tonight could not be prouder of the response of Americans. When they see their neighbors and they see their friends, they see strangers in need, Americans step up,” Obama said.

“Let’s all work together and make America still a greater volunteer nation,” said Carter, making an apparent play on President Donald Trump’s “Make America Great Again” campaign slogan.

The Georgia native said that Habitat for Humanity, a nonprofit he’s worked with for 36 years, would build 6,000 homes in hard-hit areas. It’s raised $20 million of the $100 million sought, he said.

“I too am here to urge you to give to this fine fund, and I want to thank all the volunteers,” the younger Bush said.

“There’s still work to do,” Clinton said. “It can be a new beginning if we just do what we ought to do and prove that the heart of America, without race or religion or political party, is greater than our problems.
