Ive often done this when Ive been bored. The best Beatles album was never made. You can pretty much create a "fantasy" beatles album for every year up to aroung 74/75, and then for 1980.
Its difficult as their individual sounds changed. George opted for the traditional, high production, sound via Phil Spector, and Paul went for a rawer sound. Lennon went minimalist on Plastic Ono Band, and Ringo.......well he went country didnt he.
If you took the best traks from each solo album, and put them together, what you come up with is amazing. A record with Maybe Im Amazed, My Sweet Lord, God, Instant Karma, Every Night, It Dont Come Easy, Junk, What Is Life, and that is just the songs from 1970 (in which they'd already released the lovely Let It Be album).
The mnd bggles.
