Hour 2: Everyone’s got a love story. What’s yours? We’ll explore StoryCorps’ most compelling narratives on love, courtship, sorrow, and commitment this hour with StoryCorps founder and MacArthur “genius” grant recipient Dave Isay, whose new book is “All There Is: Love Stories from StoryCorps” (The Penguin Press, 2012). He’s in town to speak to Arts & Letters Live at the Dallas Museum of Art this evening.
