Before he wrote the definitive narratives of Bob Dylan, The Beatles and now Led Zeppelin, Bob was a business manager who was there for the discovery of Bruce Springsteen and flew around the globe with Elton John. Bob tells Marc how he merged his experience in the business with an investigative approach to these music biographies and then extended it to other subjects like Woodstock, European cooking, Julia Child and Ronald Reagan.
