Katy Perry, Elton John Perform at Hillary Clinton Fundraiser In New York

Tickets to the "I'm With Her" concert cost up to $2,700.

Elton John did an 8-song set, garnering a standing ovation after each classic. The crowd sang along to “Tiny Dancer” and “Your Song." He dedicated his final song of the night, “Still Standing,” to Hillary Clinton, who was in the audience.

Katy Perry concluded the three-hour affair and made her own dedication to the Democratic presidential candidate as she sang “Unconditional."

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

Chelsea Clinton also sang her mother’s praises and a hoarse President Bill Clinton, who has aggressively been campaigning for his wife, spoke fondly of meeting his wife 45 years ago this month.

“I want you to stay with her. Nominate her! Thank you!” exclaimed the president as he was joined on stage by Hillary Clinton.

Although her comments were brief, Clinton declared tonight “Super Wednesday,” and added "I’m running for president because I want to break down barriers."

The concert benefited the Hillary Victory Fund. There were 11 sponsors of this fundraiser who gave more than $100,000. The campaign is expected to raise millions of dollars and organizers said most attendees were first-time campaign donors. Tickets ranged from $125 to $2,700.

Clinton spoke earlier in the day at a rally at the Jacob K. Javits Convention Center on Manhattan's west side in front of more than 5,000 people.
