The a cappella group Six13 have debuted their annual Chanukah production! This year, it's a medley of familiar tunes from the Broadway musical West Side Story. They channel the Sharks and the Jets as they sing about the Jewish Festival of Lights and the history behind it. While you know the songs from the 1961 movie, the newest film version of West Side Story is due in theaters on December 10. Chanukah begins at sundown on Sunday and lasts until the evening of December 6. Chag Chanukah same’ach!
