Do you think that the Beatles would have sounded more like Wings if they had stayed together?
Maybe John Lennon leaves or stays. Paul at this time was their leader.
If John left, then maybe George would have written and sung more Beatles songs. Maybe some McCartney- Harrison penned songs.
Ringo makes movies between records. Maybe he drags Paul and George into some of them.
Or Paul ends up bullying George and Ringo, becomes the main songwriter with George and Ringo doing a few songs on each album of which are basically "Wings" records.
