As it was well put by Al Kooper (the man behind the organ on “Like a Rolling Stone”), “Bob is the equivalent of William Shakespeare. What Shakespeare did in his time, Bob does in his time.” Christopher Ricks, editor of T. S. Eliot, Samuel Beckett, Tennyson, and The Oxford Book of English Verse, has no argument with Mr. Kooper’s assessment, and Dylan is attended to accordingly in this authoritative edition of his lyrics.
