"So How Come (No One Loves Me)"

I recently listened to a two-disc set of the Everly Brothers that includes "So How Come (No One Loves Me)."  Yester-day I was thinking about the song and realized something about it that also holds true for the version that the Beatles did live on the BBC.

Each verse is basically:

They say that ev'ryone
Needs someone
So how come no one
Needs me

with later iterations replacing "needs" with "wants" and then with "loves."  (Compared to the Everlys' version, the Beatles flip the order of the first two verses.  The Everlys sing "needs" and then "wants"; the Beatles sing "wants" and then "needs.")

There really isn't a rhyme scheme here; it's just "-one" rhymed with itself, which illustrates the speaker/singer's loneliness and solitude.  It's just "one," "one," "one."
