For almost 50 years, Dave Hadfield has followed the genres of music that grabbed his youthful heart and mind. Now, in 'All the Wrong Notes' he has written not just a musical memoir, but a personal and social history of the last half-century. Like a Zelig with a finger in his ear, he has been where folk music has happened and describes it, affectionately but warts-and-all, in a way it has never been described before.
