Personal Similarities Between Paul and Edward Lear

In Paul's Paperback Writer, he compares himself to the children's nonsense verse author, Edward Lear.  What was Paul trying to clue people in on?

After the last American Beatles concerts, Mal Evans was going to be more of a personal attendant to The Beatles.  I think this is the plan hinted to by Paul in the April, 1966 song.  This, apparently, never happened because something happened to Paul in that time, and, instead, Mal Evans accompanied Paul's replacement  on trips.  Edward Lear had an Albanian Christian man who was basically his manservant and accompanied him on his European travels.

Edward Lear was a lifelong bachelor, not by choice.  In several of his poems, including The Dong with the Luminous Nose and The-Yonghy-Bonghy-Bo, Lear writes about his loneliness and his desire to marry a certain girl.  For instance, The Dong with the Luminous Nose has the lines:

          But when the sun was low in the West,
          The Dong arose and said;-
          'What little sense I once possessed
           Has quite gone out of my head!' -
           And since that day he wanders still
           By lake and forest, marsh and hill,
           Singing -- 'O somewhere, in valley or plain
           Might I find my Jumbly Girl again!
           For ever I'll seek by lake and shore
           Till I find my Jumbly Girl once more!'

We know that Paul was infatuated with Jane Asher and that their relationship was not working out.  Again, the parallel with Lear.  (BTW, as I pointed out in earlier posts, John and George sang the children's song, Frere Jacques in background vocals on Paperback Writer and the line, "Ding Dong bell" might be a pun on the Dong poem.)

The other two health parallels are speculations but . . .
The first is that Lear had epileptic seizures.  If Paul was being experimented on in a hyperbaric oxygen chamber as I think he was, he very well could have had seizures from the poisonous effects of oxygen at high pressure:  it causes convulsions.
The second health problem Lear suffered from was asthma and bronchitis.  Again the Paul-is-dead song, I Am The Walrus, has the line:  "Expert, texpert, choking smokers."
