Question: When did Mary Barrett's father die?
Sentence (from "Irving Berlin"): " Over the years he was known for writing music and lyrics in the American vernacular: uncomplicated, simple and direct, with his stated aim being to "reach the heart of the average American," whom he saw as the "real soul of the country." In doing so, said Walter Cronkite, at Berlin's 100th birthday tribute, he "helped write the story of this country, capturing the best of who we are and the dreams that shape our lives."
