Author Duane Tudahl joins Craig for a discussion about his book PRINCE AND THE PURPLE RAIN STUDIO SESSIONS: 1983 AND 1984. A Prince fanatic with an impressive resume going back several years, Duane tells the story about procuring a stack of Prince's session documents from Sunset Sound and how interviews with those who worked with Prince folded into an impressive work which is - in Craig's opinion - the ultimate look at the Purple Rain years.
