Rahway, NJ - Last year, a film crew documented the high school's production of Mary Poppins and the journey through to opening night along with five other schools across the state. The documentary, I Can't...I Have Rehearsal, premieres on May 17 at 8 PM on NJTV (Verizon 523 – many places it is channel 12).
