Join Thomas Hampson for a program showcasing the songs of Stephen Foster. "Stephen Foster's music is the trunk of the tree of American song, sturdy with songs we love to sing," says Hampson. In this program he interviews Ken Emerson, author of Doo-Dah! Stephen Foster and the Rise of American Popular Culture. They'll explore Foster's music, the varied artistic roots he drew from, and the musical branches that grew from his work.
