The relationship between John Lennon and Paul McCartney was the dynamic centre of all that the Beatles did, of all they achieved as musicians and as cultural icons. Books about the Beatles abound, but none of these books have provided more than a cursory analysis of the relationship between these two men, and none have focused so intently on how this often tumultuous partnership affected their songwriting collaborations. Noted rock biographer Geoffrey Giuliano delves into the little-known details of John and Paul's rocky friendship to reveal how what was happening in their lives influenced their songs. He analyses the songs and the albums, addressing each musician's respective contributions in writing and recording. In addition, Giuliano provides a discography, a chronology, and information on songs written for other artists and songs that were never released commercially. Two of Us is a unique in-depth look at the rise and fall of this complicated and contentious songwriting team.
