Review: 'All You Need Is Love: The Beatles In Their Own Words'

According to its press release, Peter Brown and Steven Gaines's All You Need Is Love: The Beatles In Their Own Words is "A LANDMARK ORAL HISTORY ON THE BEATLES" (their caps). 

There are several problems in that last sentence: 

A) Only 20% of All You Need Is Love consists of The Beatles' own words (The Beatles being Paul, George, and Ringo, but not John). The other words are supplied by Yoko Ono, Cynthia Lennon, Pattie Boyd, Maureen Starkey, Derek Taylor, Neil Aspinall, "Magic" Alex Mardas, and twenty or so others in or around The Beatles' circle.
