So I'm sure you can find the words yourself (sorry!) but here are some more accurate
than other ones I have found on the web. This should be in the correct key for the 
song.

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


   Bb (x1333x@1)             FIt (133211@1)started out as a feeling
           Gm (355333@1)        EmWhich (022000@1)then grew into a hope
           Bb (x1333x@1)           FWhich (133211@1)then turned into a quiet thought
           Gm (355333@1)               EmWhich (022000@1)then turned into a quiet word
    F (133211@1)                 F7And (131241@1)then that word grew louder and louder
 Bb (x1333x@1)                 Eb'Til (x43121@3)it was a battle cry
          EbI'll (x43121@3)come back
        F (133211@1)  GmWhen (355333@1)you call me
Bb (x1333x@1)       F (133211@1)     EbNo (x43121@3)need to say goodbye

play around with the chords so they fit to the words and the rythme.
Hope I helped:)
