Before You Exit - Some Nights chords

I realised that when Before You Exit covered 'Some Nights' by Fun., they changed 
it a bit, so I decided to do a BYE version. There may be a few mistakes, please 
tell me if there are :) 
      Thanks, Jess :)
P.S. The chorus at the start is just vocals, but I put the chords on here (in brackets) anyway. :)



(C                       F            C)
 Some nights I stay up cashing in my bad luck.
(F             C         G)
 Some nights I call it a draw.
(C                            F                 C)
 Some nights I wish that my lips could build a castle.
(F              C                 G)
 Some nights I wish they'd just fall off

       F         C           F         C
But I still wake up, I still see your ghost.
               F         C          G
Oh Lord, I'm still not sure what I stand for, oh.
