Regina Spektor's song from the end credits of the movie Prince Caspian.

(capo on 3rd fret)

                  
It started out as a feeling
                    
Which then grew into a hope
                       
Which then turned into a quiet thought
                            
Which then turned into a quiet word
                      
And then that word grew louder and louder
                   
'Til it was a battle cry
           [bad word] back
            
When you call me
                 
No need to say goodbye

                        
Just because everything's changing
                                     
Doesn't mean it's never been this way before
                       
All you can do is try to know who your friends are
                    
As you head off to the war
                 
Pick a star on the dark horizon
             
And follow the light
             [bad word] back 
          
When it's over
               
No need to say goodbye
                       
 [bad word] back 
          
When it's over
               
No need to say goodbye

                      
Now we're back to the beginning
                                  
It's just a feeling and no one knows yet
                          
But just because they can't feel it too
                              
Doesn't mean that you have to forget
                     
Let your memories grow stronger and stronger
                       
'Til they're before your eyes
             [bad word] back
             
When they call you
               
No need to say goodbye
             [bad word] back
             
When they call you
               
No need to say goodbye
