Which Beatles member wrote these songs? – amazing charts

If you’re a Beatles fan – and since you are on this page, chances are high that you are – you have to check out these amazing charts.
Let’s take the first one. It shows which member of the band wrote what song. It also shows the percentage of their contribution if the song was a result of a collaboration two or more band members.

Penned by a single author, or is it a collab?

We have pure John Lennon songs like “Please Please Me”, “All I’ve Got To Do”, “Yes It Is” from the early era. Or there’s “Strawberry Fields Forever” and “The Continuing Story Of Bungalow Bill” from the later Beatles. And also pure early Paul McCartney tunes like “All My Loving”, “I’ll Follow The Sun”, “I’m Looking Through You”. Or from later times “Martha My Dear” and “Maxwell’s Silver Hammer”. Every song is indicated in the chart, including 50/50% collaborations like “I Want To Hold Your Hand” or “Baby You’re A Rich Man”. Then there are the George Harrison songs like “Don’t Bother Me” or “Blue Jay Way”. Even the two tunes penned entirely by Ringo Starr: “Don’t Pass Me By” and “Octopus’s Garden”.
Notice how other than the occasional collaborations, the members have become more and more individual as the band developed (and as they got fed up with each other gradually).
