Capo in the 3rd fret.(during Grammy Awards 2011 performance)
Capo in the 4th fret.(in original song)


E5                  C5
Im about to lose my mind
                         D5
you've been gone for so long
                    D5
I'm running out of time
           C5
I need a doctor
            C5
call me a doctor
          B5
I need a doctor, doctor
                    E5
to bring me back to life
