I Want The One I Can't Have Chords
This is copied from the tabs posted by Craig Ablitt. I changed some of the Bm and C chords to Bm7 and Cmaj7
chords and a few other small tweaks based on the website SmithsonGuitar.com where they have multiple songbooks 
available. Otherwise, this is mostly the tabs originally posted by Craig Ablitt, who did a great job with the 
song.
Intro
G C D-->Bm7
Verse
       C             D      Em Bm C D (QUICKLY)  G

     Em Bm C D (quickly)
Come round ...
Chorus
         Am             Bm7         
'Cause I want the one I can't have 
Cmaj7                      D
   And it's driving me mad 
         Am                  Bm7      Cmaj7    D
It's all over, all over, all over my face 
Em until next verse;
Verse 2 
(note slight change from first verse, with no G after first line, straight into C again) 
       C             D      Em Bm C D   
On the day that your mentality 
C                    D    Em Bm C D
Catches up with your biology 
Chorus 2
  Am             Bm7 
I want the one I can't have 
Cmaj7                     D
  And it's driving me mad

It's all over, all over, all over my face 
Verse 3
G        C
A double bed
      D                  Bm7 
And a stalwart lover for sure 
C             D             Em  Bm C D
These are the riches of the poor 
Same as above except Em Bm C D progression played twice
A double bed 
And a stalwart lover for sure 
These are the riches of the poor 
Chorus 3
      Am             Bm7

Cmaj7                    D
  And it's driving me mad 
Am                           Bm7      Cmaj7   D 
It's all over, all over, all over my face 
Em until:
  C            D                 Em Bm  C D
A tough kid who sometimes swallows nails 
C        D             Em Bm C D
Raised on Prisoner's Aid
            Am                    Bm7
He killed a policeman when he was thirteen
    Cmaj7                     D 
And somehow that really impressed me
         Am          Bm7     C   D  
And it's written all over my face 
Then the intro: G C D->Bm7
    C             D             Em Bm C D
Oh, these are the riches of the poor 
Then G C D-->Bm7 again
C             D             Em Bm C D (play chords twice)
These are the riches of the poor 
Chorus
  Am             Bm7
I want the one I can't have
Cmaj7                     D   
  And it's driving me mad
     Am          Bm7   Cmaj7   D
It's written all over my face  
Em until:
Last Verse
       C             D      Em Bm C D
On the day that your mentality 
C                    D    Em Bm C D
Catches up with your biology 
           Am                 Bm7 
And if you ever need self-validation
     Cmaj7                           D
Just meet me in the alley by the railway station 
Am       Bm7      Cmaj7   D
It's all over my face 
Outro is Em continuously
