This Was The Last Song Recorded By All Four Beatles
In the history of popular music, no band has had their catalog picked apart to the extent that the Beatles have. Every aspect of every song has been analyzed. From what key the song was written in, to what it was written on, to who wrote it, to where it was recorded. Sometimes, the minutiae of different takes or demos of the same song have been obsessed over. This is just another example of why the Beatles are thought to be the most popular and successful band ever.
According to Far Out, the first song the Beatles ever recorded is a more difficult question to answer than one would think. They booked studio time as early as 1958 while still known as the Quarryman, but their first song recorded by John Lennon, Paul McCartney, George Harrison, and Ringo Starr was "Love Me Do."
