Paul McCartney: The Life by Philip Norman

As a Beatles fan, I have known of Paul McCartney most of my life, but after reading this biography I now feel like I know him, too. The author does a fine job exploring Sir Paul's musical genius as well as his personal shortcomings. As a result, I was able to move from idolization to admiration of this unique individual.
ELPL has both the print, eBook, and audiobook versions. I really enjoyed listening to all the accents the narrator, Jonathan Keeble, used. He does great Paul and John imitations.
