Katy Perry, Elton John rock Radio City in fundraiser for Hillary Clinton

Fresh from her Super Tuesday victories, Democratic presidential frontrunner Hillary Clinton went home to New York Wednesday night for a stars-and-stripes concert fundraiser headlined by two of her biggest pop-music supporters, Katy Perry and Elton John.

Clinton, who spoke briefly, called the night "Super Wednesday," according to ABC News.

Some 6,000 people packed Radio City Music Hall for an "I'm With Her" rally that also featured Andra Day and on-stage appearances by other Clinton supporters, including Oscar-winners Jamie Foxx and Julianne Moore, plus brief remarks by former President Bill Clinton and daughter Chelsea Clinton.

Perry, who might be Clinton's number-one celebrity admirer, whose song Roar is one of Clinton's campaign anthems, and who campaigned for Clinton in Iowa last year, was dressed in a sparkly star-spangled pantsuit and performed on a stage bathed by red-white-and-blue lights reproducing the American flag.

“I’m not voting for (Clinton) because she’s a woman,” Perry said between songs, according to Variety. “I’m voting for her because she’s the right person for the job.”

Hers was the three-hour concert's concluding performance. She dedicated her rendition of Unconditional to Clinton.

“I sing this next song for her because I do believe this woman shows unconditional love,” Perry said.

John, who got multiple ovations for his 30-minute set hits, including Tiny Dancer, told the crowd that Clinton is the only candidate who can get elected in the fall.

“This is a very important year for America, and she’s the only hope you have,” said the British-born John, who is a legal resident of the USA but not a citizen. He can't vote but he can donate to political campaigns.

John dedicated his final song of the night, Still Standing, to Clinton.

Meanwhile, another Clinton supporter tweeted tributes.

The concert, which benefited the Hillary Victory Fund, was sponsored by donors who have given more than $100,000 each to Clinton's campaign.

The performers are expected to donate their performance fees to the campaign. The Clinton campaign did not immediately say how much money the concert raised.

Moore introduced Chelsea Clinton, saying, "Hillary has always fought for us and now it’s our turn to fight for her.”

Bill Clinton said his wife would be the "change-maker" the nation needed.
