I just read something that was very interesting about The Beatles. It is a book called The Present at link
There is a section about The Beatles that starts at page 206. The author gives a first hand perspective of what it was like to grow up when the music was being released. He goes on to reflect on how The Beatles are prophets, and that the hidden messages in their songs are easy to see when you realize what they are. This book explains everything in detail and is a highly recommended read for any Beatles fans.
This book completely changed my perspective on The Beatles and now I love their music more than I ever have before.
