Noted biographer Phillip Norman will write what is being billed as the "definitive biography" of Paul McCartney, which will be published in 2015, according to USA Today. The still-untitled book has McCartney's approval, and will be published by Reagan Arthur. Norman is no stranger to writing about the Beatles, having published the groundbreaking 1981 book Shout - The Beatles In Their Generation and 2009's John Lennon: The Life. Norman's other works include last year's Mick Jagger biography, 1994's The Stones, along with 1984's Elton John, and 1996's Rave On: The Biography Of Buddy Holly.
