I first heard the Beatles first single*, Please Please Me, on an acetate in the offices of Dick James, a publisher of their music. It was an obvious smash hit record. Everyone knew it. Everyone.
The Beatles' album Please Please Me was incredible to listen to – new, fantastically energetic … up to this point long-playing records were basically a bunch of singles put out to capitalize on the success of the singles. But John realized that they could actually be a collection of music that made a statement, and after Please Please Me that's what they did. Of course it affected every band; the Beatles opened up the door and we all ran through it.
How could you not be affected by their energy and song writing abilities. They, and Bob Dylan, showed us the way to create music that meant something other than "moon, june" lyrics
