'In this illuminating book Jon Stewart invites readers to explore the work of John Lennon and Bob Dylan through the filter of three key themes – protest, history, and spirituality. There is a simplicity and an elegance to this approach, and the result is a compelling and revealing analysis of the very familiar music of two canonical singer-songwriters.' Sarah Hill, University of Oxford '… the dual biography, evaluating the extent to which the pair illuminated - and at times rejected - one another's creative achievements and political sensibilities, should fascinate most readers.' Johnnie Johnstone, Shindig!
