I don't think getting the whole story. John and Paul emerged with the
equivalent of a certificate, of not a degree, from a source such as the
prestigious Juilliard...
(btw, Miles Davis was a Juilliard drop-out because he got bored with
their teaching, but you can hear his excellent training in the elegance
of his interpretations...)
Since both John (hero, Tamino) and Bob (fiend, Monostatos) are both part
of the opera The Magic Flute, they were likely both part of the
experiment.
It seems to me Bob had a team right from the start. They either wrote
or helped him write some of his songs. They also provided him with
almost unheard of opportunities, such as playing Carnegie Hall when he
was still an unknown.
Although John was naturally gifted, he and the rest of the Beatles may
have had a similar team, in this case, to elevate what they were doing,
both in composing and performing. The objective was for them to create
a frenzy.
The ultimate objective of this experiment, I think, was to use the
emotions of young people, just coming out of the constrictions of the
fifties, to, in effect, change history. And because they were using John
and Bob, they were using the energy of the Mozart vortex to do this...
And,of course, conveniently, they were keeping the power of the
Zauberflote in the hands of the guys...
just my 2 cents...
