Some people wait a lifetime for the chance to perform at the Lincoln Center in New York City. For Sarah Burke, that opportunity is coming early in her career. The 20-year-old actress and singer who grew up in Lackawanna County will be performing at the Lincoln Center’s Spring Gala Musical Celebration of Herman, Menken and Sondheim on Tuesday alongside stars such as Rita Moreno. “When I saw the email, I almost died,” Burke said. She was recommended for the performance by a teacher from the American Musical and Dramatic Academy, where she attended college, and said the chance to honor composers Jerry Herman, Alan Menken and Stephen Sondheim is “surreal.” “It means the world to me,” Burke said.
