Among the many films being screened at the Tribeca Film Festival is a documentary story that unfolded right here in New York. It’s called “Once In a Lullaby” and tells the story of Staten Island’s most well known school choir – and their journey to perform at the 83rd annual Academy Awards. We’ll hear all about it from the film’s director, Jonathan Kalafer, and PS22 chorus teacher Gregg Breinberg.
