Every holiday season during “The Brown-Forman Nutcracker,” the Louisville Ballet’s cast swells with student dancers. This year, there are 118 spread over two casts. They play Christmas party kids, angels, tiny soldiers and rats – some are as young as seven years old.WFPL’s Erin Keane goes backstage to visit the jockeys during rehearsal and chats all things Nutcracker with Christine Carrigan, a long-time volunteer who works as the children's cast coordinator, and Helen Daigle, a company dancer who choreographs the student dancers. Remaining public performances of “The Brown-Forman Nutcracker” are Friday, Saturday and Sunday this weekend (Dec. 13-15) and next (Dec. 20-22).
