SUNRISE, Florida (CNN) -- Drama students past and present shared the stage Monday night for a benefit concert featuring stars and survivors of a school shooting in Parkland, Florida.
"From Broadway With Love: A Benefit Concert for Parkland, USA" featured a star-studded roster of Broadway and television entertainers, including "Glee" actor Matthew Morrison, "Crazy Ex-Girlfriend" star Rachel Bloom and award-winning recording artist Deborah Cox.
More than 4,700 people attended the concert at the BB&T Center in Sunrise, Florida, organizers said. The celebrity entertainers performed with Stoneman Douglas students and local arts groups, including the Student Choir of Broward and Dance Theatre of Broward, on a program that ranged from upbeat and inspirational to reflective and moving to fun and silly.
Despite the circumstances that brought them together, Bloom said the chemistry among the performers was instantly palpable. After all, the celebrity performers were once theater kids, she said.
"Tonight is about them and I'm happy to be here and support them. The kids from Marjory Stoneman Douglas are doing what the arts are supposed to do -- they are channeling their intense feelings and rage and thoughts into their art, which is a way to communicate with people and make the world better," Bloom said in an interview before the show.
"This is an example of why theater and the arts in schools is so important," she said. "It makes me proud to be a fellow theater kid seeing what all these people are doing with theater and music."
'A healing night'
The concert opened with a stirring rendition of Leonard Cohen's "Hallelujah," sung by "Mamma Mia!" actress Carrie Manolakos and a choir of Marjory Stoneman Douglas High School students. Former "American Idol" contestant Justin Guarini performed a song written by a Stoneman Douglas student.
Deborah Cox crooned "I Will Always Love You" as images of the 17 victims flashed behind her. The dance group that victim Jaime Guttenberg belonged to staged an emotional performance that elicited cheers of "We love you, Jaime" as the dancers left the spotlight.
Moments of levity punctuated the somber tone, such as Bloom's rendition of "F---ton of Cats" and Erich Bergen's performance of "Man in the Mirror," all with backup from Stoneman Douglas students. "Glee" star Matthew Morrison and Stoneman Douglas senior Kali Clougherty nearly stole the show with a duet performance of "Somewhere Over the Rainbow."
Stoneman Douglas sophomore Tanzil Philip, who hit the high note near the end of "Seasons of Love," said performing in the show was difficult during the memorial parts. "But by the end, the whole thing felt healing," he said. "It was a healing night."
'Everything we're doing is for them'
Working with the teen performers made the February 14 shooting feel all the more real, Broadway performer Donna Lynne Champlin said. But in the frenzied excitement of rehearsals, it was easy to momentarily forget why they were there, the "Crazy Ex-Girlfriend" actress said.
"We're sort of looking at our younger selves and going, 'When we were your age we were writing songs about rainy days and broken hearts, and here you are writing songs about losing numerous friends.' I think they're extraordinary" she said. "I can't even imagine what their reality is like."
The concert was the culmination of weeks of intense preparation, Stoneman Douglas junior Sawyer Garrity said before the concert. But she never forgot what brought everyone together.
"There's been some really awesome moments because of this, but it's hard to feel excited or happy about them because you realize what happened and why we're getting all these opportunities," she said.
With the help of composer Duncan Sheik, she and another student composed a song based on a poem written by shooting victim Alex Schachter. His parents asked them to write the song after their first performance at a town hall after the shooting, she said.
"This song is for him. He's going to live on through this song and through this poem he wrote," she said.
"In the end, everything that we're doing is for them and everything that we're doing is so that they'll be remembered -- all the 17, and even the ones who were injured and anyone hurt by gun violence."
