B                                 Abm         
Mary, Mary-belle within a bird-cage cell,
                Eb                   F#
All your neighbors know what your mother sells
B                              Abm                     Eb            F#
But you carved out a name; you carved out a name for yourself

           B
Look out, look out
           Abm
Look out, look out
          F#
Look out, look out
          B
Look out, look out
          Abm
Look out, look out
          F#   Ebm         B             
There are murders about

B               Abm
Guinea pig in a twisted mouth
          Eb              
Through a hole to the railway
         F#
And Brian?s face down
B
Keep your wits
          Abm
He will not be missed
        Eb                    F#
He didn?t have a family to begin with

You could also use capo on 4th fret and play G  Em  B  D for the verses and G  Em  
D, G  Em  D  Bm for the chorus.
