Director Roberta Grossman and producer Marta Kauffman collaborate to explore the history of the eponymous Jewish celebratory song "Hava Nagila" in this documentary featuring interviews with an entire host of renowned celebrities and musicians, including Leonard Nimoy, Regina Spektor, Harry Belafonte, and Glen Campbell. A ubiquitous tune, it's played at bar mitzvahs, weddings, and virtually anywhere people are having a good time. But where does it come from, and what role does it play in illuminating Jewish history? Grossman and Kauffman seek the answers to those questions and more as interview subjects share vivid memories of the joyous song. ~ Jason Buchanan, Rovi
