"John is an original. New ideas just come to him. Paul has great originality, but he’s also an arranger. He can get things done, which John can’t, or can’t be bothered trying. They do need, and they don’t need, each other. Either is true. Paul is as talented a composer as John. They would easily have done well on their own. The most amazing thing about them is that by coming together they haven’t become the same, they haven’t been influenced by each other. They’re each still different, each is still himself. Paul still does sweet music, like “Michelle”, that sort of melody. John writes bumpy music. Working so long together hasn’t rubbed out the differences, which I think is amazing.” - Astrid Kirchherr in The Beatles Authorized Biography, Hunter Davies
