The Changeling
The Doors
LA Woman, 1971

I was just randomly listening to the song, and its pretty simple, so I figured it out, 
mostly on the organ part.
The song is based off the chord A(#9).  Its just an A7 chord with a C on top essentially.

Organ solo over A-G-A notes, then the guitar starts the A(#9) chord.

Verse:
          A(#9)x3 (notes only:) E G-E 
and repeat half A million times...
I live uptown...

(notes)   C  C     A    A   G      G    E  G     E    G
But I've  ne-ver  been  so  broke  that  I could-n't  leave

(notes, listen to the song for the rhythm.):
A-A-A E-G-A   C   
G-A-G-E-G-A
Town...                         See me change...


(notes as well)   A5  G5   A5      A5  G5  A5  A5     G5   A5   A5  G5  A5
I'm the         air you breathe  food you eat  friends you meet  in the...

Hold a Am essentially under the first solo, the organ messes with the chord a bit but in 
its Am (adding a 7 here and there).

Repeat the chorus as before
Then the second time, bring it all up a half step (from A7 to Bb7 now), and its gonna 
that way for the rest of the song.

So you're now taking everything from before up a half step.
Bb#9 (technically an Bb, but for the sake of simplicity) becomes your chord, with a F 
Ab the bouncing notes.

During the second solo, start on an Bb5, and it doesn't get a third until after the 
double solo part (listen to the song), when the organ makes it a Bb major (adding the D), 
a Bb7 (adding the Ab) as it nears the end of the solo.

And just keep jamming that chorus lick in Bb and you have the song in a nutshell.
