Book excerpt: Writing The 100 Greatest Rock'n'Roll Songs Ever was a labor of love. Written while on Sabbatical leave from my day job, it is one listener's snapshot of the genre, from the mid-'50's to the present, filtered through my personal life experiences. My purpose for writing this book was to acknowledge the major role that the music has played in my life. My wish for the reader is to stimulate memories of your own favorite songs and of the rock'n'roll vernacular and experiences shared by many of us.
