Korpens Saga Chords

Okay this is my first ever to do this..I recently started playing guitar and can 
only do basic chords and this seems right to me..
[ Tab from: http://www.guitartabs.cc/tabs/f/finntroll/korpens_saga_crd.html ]
Am                G          Am
Jag såg min här av troll och vätte
Am                   G      Am
Slappa spjut så långt ögat mätte
                    
Am                     G       C
Tusende kroppar alla döda och svala

C                    G        Am
Min arme ur skogen nu låg i dvala.

you can play Am G C through the whole song, I have an acoustic guitar so it 
doesn't sound bad..hope this helps Enjoy ~HAILS~
