I find it implausible that 4 school chums from Liverpool turned out to be musical geniuses. It's much more plausible that they were reasonably smart, really loved music, and worked very hard learning to play. Once one learns to play well, moving into composition is a natural step.
It's unsurprising that the Beatles' music they created as a group was better than what they did afterwards (much better). After all, if you're John Lennon, who is going to tell you your latest song sux, and btw, here's an improvement to it? Nobody but a fellow Beatle.
