Airs Thursday, April 2, at 7 p.m. This special is a new production in a series of a conversation about Passover, one of the most important and most beloved holidays on the Jewish calendar. Larry Josephson, a secular Jew who now wants to know more about the religion of his grandparents, asks Rabbi Ismar Schorsch, Chancellor of the Jewish Theological Seminary, to explain the meaning of Passover in a post-9/11 world. Dr. Schorsch tells Larry the story of Passover -- its history, rituals and foods, and the origins and structure of the Seder. The music of Passover, sung by some of the best cantors and choirs in the world, is artfully woven in and out of the conversation. The music was chosen by Cantor Marcia Tilchin, the Associate Producer. The program was developed and produced by Larry Josephson, and edited and mixed by Peter Zanger.
