the general chords of the song are:
Bb, F, Gm, Eb


   Bb               F
It started out as a feeling
           Gm          Em
Which then grew into a hope
           Bb             F
Which then turned into a quiet thought
           Gm                 Em
Which then turned into a quiet word
    F                   F7
And then that word grew louder and louder
 Bb                   Eb
'Til it was a battle cry
          Eb
I'll come back
        F    Gm
When you call me
Bb         F       Eb
No need to say goodbye
