A big part of Dylan's unprecedented allure, beyond his own extraordinary songwriting ability and mesmerizing concert performances, is his gift for uniquely covering hundreds of songs by other talented singers and songwriters, both known and unknown. Until now our knowledge of those songs, their creators, their antecedents and what Dylan did with them was a hodgepodge of missing information, misinformation, mangled information and guesswork. Derek Barker, in this wonderfully written, extraordinarily entertaining and thoroughly informative book, has righted all those wrongs. Thank heavens! The book is structured well, is fun and easy to read, plus, it answers all the questions even the most devote Dylan fan needs answered. I use it as a reference guide for my Dylan class as well as on my Dylan radio show when anyone wants to know whether Bob's covered a song or not, when he covered it, how often and, more importantly, what did he or did not add to it. Complete your Dylan library, buy and love this book, just as I do.
