''The Impossible Dream'' is an in-depth biography that traces the career of one of the most successful bands in pop history. In addition to assessing and analysing the talent and appeal of the enigmatic Scott, the author also covers the history and contributions of the other 'brothers', John and Gary, and provides a thorough analysis of all three men's careers both as individual artists and as a group, from 1963 to 1978. Drawing on decades of archive interviews with the band (some previously unpublished), and many new interviews with backing musicians, record label staff and producers, ''The Impossible Dream'' is the definitive telling of The Walker Brothers' story.
