Your life's a mystery
Fm
mine is an open book
Cm
If I could read your mind
Fm                      Ab
I think I'd take a look
Bb          Cm
I don't care
    Ab Bb        Cm
Baby, I'm not scared

(same base:)
What have you got to fight?
What do you need to prove?
You're always telling lies
and that's the only truth
I don't care
Baby, I'm not scared

(Chorus:)
Cm                       Bb
Tonight the streets are full of actors
Cm             Bb
I don't know why
    Gm7              C7
Oh, take these dogs away from me
Gm7                C7
before they, they bite

( Cm Fm )
What have you got to say
of shadows in your past?
I thought that if you paid
you'd keep them off our backs
( Ab Bb Cm )
but I don't care
Baby, I'm not scared

(keep it:)
What have you got to hide?
Who will it compromise?
Where do we have to be
so I can laugh and you'll be free?
I'd go anywhere
Baby, I don't care
I'm not scared

( Cm Fm Gm Ab Gm )

Bb       Cm

   Ab Bb        Cm

(Chorus 2x with this variation:)
Tonight I fought and made my mind up
I know it's right
I know these dogs still snap around us
but I can, I can fight

  Cm             Fm
If I was you, if I was you
   Gm                   Ab
I wouldn't treat me the way you do
   Cm            Fm
If I was you, if I was you
    Gm                  Ab              Gm
I wouldn't treat me the way you do - you
