In 1964, legendary radio host and oral historian Studs Terkel brought a young, virtually unknown songwriter from Hibbing into the studios at WFMT Chicago. That interview with a young Bob Dylan is one of dozens he has transcribed into a collection of conversations about music. Terkel says the book's title, "And They All Sang: Adventures of an Eclectic Disc Jockey," comes from an interview with conductor Leonard Bernstein. He talked with MPR's Tom Crann.
