Former President Bill Clinton, Janet Jackson, James Taylor, Don Henley, John Mellencamp and other famous names voiced their support for the Democratic Party -- and raised $5 million -- at the Democratic National Committee's "Every Vote Counts" concert in Washington, D.C., Wednesday night, PEOPLE reports.

In her opening remarks, presenter and former "Wonder Woman" TV star Lynda Carter, 50, joked to the politically minded crowd, "I know we're all missing 'West Wing.'"

Jackson, 36, adding a pop touch to the proceedings, came on stage in flounces of tulle and introduced Clinton as "one of the great political leaders and humanitarians of all time."

She then offered a more personal take on the nation's 42nd president, saying: "It is such an honor for me to introduce one of our country's most brilliant, effective and to me, sexiest, leaders."

"I'll be living on that introduction for a long time. And doubtless paying for it in some quarters," Clinton noted in his thanks to Jackson. He attended the fundraiser with his wife, New York Sen. Hillary Rodham Clinton.

"I want to thank my fellow aging baby boomers," said Clinton, 56, with a nod to Taylor, Mellencamp and Henley.

Quipped Henley, 55, before singing his hit, "The End of the Innocence": "We baby boomers just can't keep our mouths shut -- even if it's bad for business."
