The last Beatles album (Let It Be doesn't count as that was just reworked from the Get Back sessions), in-fighting and tension was so much that many songs don't feature the full band.
Speaking of individuals, the songs here definitely show that... John was getting bluesy with "Come Together" and "I Want You (She's So Heavy)". Paul was waist deep in "granny music" with shit like "Maxwell's Silver Hammer" that had already been bumped from The White Album and derided in the Get Back documentary. George was still riding that "While My Guitar Gently Weeps" high from the White Album with the truly great "Something" and "Here Comes The Sun". And Ringo had "Octopus's Garden", can't have them all Ringo, but you miss 100% of the shots you don't take, at least you got a badass drum solo on this album.
Then they just went their separate ways and stopped recording a month before this was released and George Martin scraped together bits and bobs to make the suite medley that ends the album.
Its The Beatles, so I'mma give it 5 stars, but the end of The Beatles is definitely a bittersweet thing.
