If you want to compare the work of John Lennon and Paul McCartney in The Beatles, you’ll find an almost even level of success. One or the other wrote and sang on the majority of songs released by the Fab Four from 1963-70. (Paul had a slight edge when it came to the No. 1 tracks.)
But their approach to writing and recording could hardly be more different. By the mid-’60s, John took a sharp turn toward the experimental and psychedelic while Paul continued recording his “silly love songs” and tracks John referred to as “granny music.”
They also went about their business in the studio very differently. While Paul could be methodical and obsessive — at times, to the annoyance of John and everyone else — he thought in very concrete terms about what he wanted.
