The first song of the concert sent a powerful message Monday night, with the singing group "Shades" performing a medley of 'Amen' and 'We Shall Overcome.'
"We sing it because of the Civil Rights Movement, but also for its everyday significance, especially in times like these," said Yale University Junior and Shades member Brandon Sharp.
After a devastating earthquake, Haiti needs help and hundreds of Yale students answered the call the best way they knew how -- performing.
"Have you ever heard music that you caused your breath to catch, or you get a lump in your own throat? Music and tragedy live in that emotional part of the world. It's the same thing," said Yale Professor of Music Tom Duffy, who helped organize "Help Can't Wait - Haiti Relief Concert."
Put together in just four days, 14 performance groups came together to perform at Woolsey Hall.
"As citizens in the world, we've got a responsibility to help out in the ways that we can and this is one way that we can help out," said Yale freshman and Concert Band member Nathan Prillaman.
$20 was the suggested ticket price. $10 for students.

Yale Junior Hyatt Howard said he didn't have much to give, but he wanted to help and support his fellow students by buying a ticket.
"I decided I could give a little and come out here," Howard said.
But a look at the cash box showed some paid with $100 bills. One student brought a plastic bag full of 975 dollars, all collected from a bake sale.
Whether performing on stage or listening in the crowd, Yale's Woolsey Hall was packed with those who wanted to bring harmony back to Haiti.
Organizers hoped the concert would raise $100,000 for relief efforts.
