The basic chord progression is C-G-Am / Am-G-C, however the G isn't played like a chord.
It's simply a filler (transition) between the Am and C.
Listen to the song to understand what I mean. 

[Verse]

Am                   G
Sweet, sweet girl dreamed some day she'd 
        C       G
be a writer

Am                            G
Swore she's never give up on her soul 
   C      G
desire

Am                  G
But leaps of faith turned to shots in the 
   C      G
darkness

Am                          G
Until she told herself that she'll never be 
     C     G
an artist


[Chorus]

Am
Don't give up on you
G                        C        G

I believe in your fever

8 years old in an apple orchard

Am                               G         

His best friend told him that his soul would 
       C      G
be tortured

Am                             G
He ran to his mother with the fear of 
     C    G
religion

Am
She showed him how to stand up
G                   C        G
And make his own decisions


[Chorus]

Don't give up on you
G                        C        G
I won't give up on you either

I won't give up on you either

Am
I believe in you
G                   C      G
I believe in your fever


[Verse]

Am                   G            C       G
Sue and her friend were lesbian lovers

Am                                                            
They moved to Vermont so they could 
G            C      G
marry each other

Am                       G
In a little house in the woods and the 
   C      G
clover

Am                                 G
They found the meaning of life and all of 
        C      G
it's wonder

[Chorus]

Am
Don't give up on you
G                        C        G
I won't give up on you either

Am
I believe in you
G                   C      G
I believe in your fever


Am
Don't give up on you

I put my faith in your fever

Am          G             C       G
We put a faith in your fever
