The Beatles music evolved significantly over the 7 years they were together. Also later in the Beatles tenure, George Harrison became a major songwriting contributor with “Here Comes The Sun”, and “Something”, which are two of the better songs the Beatles made in their final years. Most of the main hits are primarily Lennon or primarily McCartney, with the very notable exception of “A Day In the Life”, in which Lennon and McCartney wrote and sang separate parts of that very notable song.
One of my all time favorite McCartney songs is “Uncle Albert and Admiral Halsey”, released shortly after the Beatles broke up. It’s some of his best guitar work, along with “Maybe I Am Amazed.”
Although I acknowledge McCartney’s tremendous artistry and contribution to music before and after the Beatles, I feel as though Lennon’s artistry was on a different level. His songs are more profound and mystical. McCarthey was good at writing somewhat silly love songs. Lennon wrote some much deeper shit which was also more interesting musically in many cases. Of course Mccartney did throw in some major classics like “Yesterday” and “Hey Jude.” Great songs - no doubt. But to me “I Am The Walrus” and “Strawberry Fields Forever” by Lennon are so unusual, so distinctive, so brilliant. These songs are examples of why Lennon was really one of a kind, and why all the other Beatles viewed him as their main man, and why he was the main man and leader of the Beatles. He was the glue.
