The new documentary "Once in a Lullaby: The PS22 Chorus Story" follows the choir members of Public School 22 on their amazing journey from their school in Granitville, Staten Island, NY to their performance at the 2011 Academy Awards.
PS 22 is located in the Graniteville section of Staten Island, and its student body is composed of 78% black, Hispanic and Asian students.
The choir became a Youtube sensation after their videos went viral. They were once called "the best-known elementary school chorus on the planet" by New York magazine.
The group is led by chorus director Gregg Breinberg, better known as Mr. B and its memebers are mostly 5th grade students.
In December of 2010, Hollywood star Anne Hathaway visited PS 22 as a surprise guest during the choir's Annual Winter Concert and announced to the choir that they were not only invited, but that they would be singing at the Academy Awards.
With only five weeks before their big performance, the group rehearsed relentlessly. And it paid off. Their performance closing the 2011 Oscar's with a rendition of "Somewhere Over The Rainbow" was one of the most memorable moments of the night.
You can see more of their work leading up to that Oscar's presentation in the documentary, which is being released on April 29th at the Tribeca Film Festival.
