Some of our most cherished holiday songs, including “White Christmas” and “Easter Parade,” as well as “God Bless America,” were written by the prolific composer-lyricist Irving Berlin (1888-1989), a Jewish immigrant from Russia. Mo Rocca talks about the remarkable life of Berlin, who wrote hundreds of standards, with his granddaughter, Katherine Swett; Broadway musical director and conductor Andy Einhorn; Josh Perelman, Chief Curator at the National Museum of American Jewish History in Philadelphia, and ultra-Orthodox singer Shulem Lemmer.
