So when youre doing the "Not my fault" part play the first F7 diagrammed for not, the 
second F7 for my, then the Bbm for fault.




A#m-6 8 8 6 6 6
F-x 8 10 10 10 8
G#-4 6 6 5 4 4
Ebm-x 6 8 8 7 6
First F7-x 8 10 10 10 11
Second F7-x 8 10 8 10 8




              Bbm          F             Bbm
Would you be upset if I told you we were dying?
           Ab                    Bbm
And every cure they gave us was a lie?
Ebm                                     Bbm
Oh! They mean it when they say we're dead and doomed
F                                       Bbm
And every single symptom brings us closer to the tomb
Eb,                                     Bbm
And who will take the credit for our swift impending fall
             F7  F7  Bbm
Because it's not my fault



the rest of the song follows this progression so yeah, and the horns are playing a 
different progression i think, but if you are playing solo this is the way to go.
