So glad the Beatles never sounded like Wings. I never liked Wings much (boring) or Paul's music on his own either. It is not the same as the Beatles music. The big factor in the Beatle sound was Lennon. Listen to the music John did between 1970 and 1980 and you will hear more Beatles like music going on there without doubt.
I feel the magic happened when they wrote together. John pulled the sound away from Paul towards some point in the middle (e.g. the Beatles) and Paul did the same too.
I think we might need
Ben to chime in here. After all he has spent quite a bit of time researching the sound. And he is quite capable of recreating it too which is damn hard.
