Excellent book about the songs of Lennon and a nice bargain - elsewhere this is: -
Much has been written about John Lennon's life and about the Beatles' music. What is often overlooked is the extraordinary solo work that John produced in the final decade of his life, 1970 to 1980. The period was a time of great creativity for Lennon in which he wrote some of his most powerful songs. Freed from the restrictions of the Beatles his style became more confessional than ever and his music gives an extraordinary insight into his life, feelings and beliefs.
