Ah,_____________ 
ah._____________  
A We E come from the land of ice and
  snow, from the midnite sun where the hot springs blow.____  
(main riff)  
The hammer of the gods  will drive our ships__ to new lands, to fight the  horde,__ singing and crying:
 E Vahala, I am coming!______A__F#m__ 
A on we sweep_ B with treshing oar,_ 
C our only goal will be the west-ern  
shore  
(Main riff)
 Ah,____________ ah.____________  
A We E come from the land of ice and snow,
 from the midnite sun where  the hot springs blow.____ 
 (Main riff)
 How soft your fields so green,  can whisper tales__ of gore,___  
of how we  calmed_ the tides of war.___ 
E We are your over lords. A on we sweep_ 
B with treshing oar,_ C our only goal will be the west-ern shore  
(main riff)
 So now you'd better stop__ and rebuild your ruins,
 for peace and trust__ can win the day despite of all your  losing.

A:     .                                                       
e:----0------------|           
B:----2------------|                                                    
G:----2------------|                                                    
D:----2------------|                                                   
A:----0------------|                                                    
E:-----------------|          
E: 
e:----0------------|                                     
B:----0------------|                                     
G:----1------------|                                     
D:----2------------|                                     
A:----2------------|                                     
E:----0------------|          
But the crescendo in the middle, 
("on we sweep, with threshing oar....) 
is actually A5 - B5 - C5:
     A5                  B5             C5         
e:-------------------------------------------------|        
B:-------------------------------------------------|         
G:-------------------------------------------------|         
D:---7------------------9--------------10----------|         
A:---7------------------9--------------10----------|         
E:---5------------------7--------------8-----------|          
If you listen carefully, A5 is played 16 times quickly, B5 is also played 16 times quickly, C5 is played 16 times, plus an extra 9. Don't forget to stop short on the 9th time!F#m is never played in the song, the beginning part is given as N.C. Let me just do the song:
          Riff 1
e:---------------------------------------------------------|         
B:---------------------------------------------------------|         
G:---------------------------------------------------------|         
D:---------4-------------4-------------4------------4------|         
A:---------------------------------------------------------|         
E:--2--2-2---2--2-2--2-2---2--2-2--2-2---2--2-2-2-2---2-2--|          
Play Riff 1 4 times while someone goes "Ahhhhhhh......" 
A     E         
 We come from the land of the ice and snow, from the midnight              E     A 
 where the hot springs blow;          
Play Riff 1 3 times with the lyrics:
The hammer of the gods .. will drive our ships to new  lands             
                                                                                                A         
to fight the horde, singing and crying:
   E                     E  A         
    Valhalla, I am coming!          
Play Riff 1 once, then:
          A5
          On we sweep -
          B5
          with threshing oar - 
          C5
          our only goal will be the western shore.
           
Then repeat everything all over again, this time with different lyrics after "We come from the land of the ice and snow...." 
 part:          
How soft your fields so green, can whisper tales of gore,         
of how we calmed the tides of war. We are your overlords...          
 After the last C5 part:          
Play Riff 1 3 times with the lyrics:          
So now you'd better stop - and rebuild all your ruins,         
for peace and trust can win the day despite all your losing.          
As you hear the word "losing", replace the last part of Riff 1 with:
                     C9
                 e:-------------------|
                 B:---3---------------|
                 G:---3---------------| 
                 D:---2---------------|
                 A:---3---------------|
                 E:-------------------|
          Then play the outro:
   Repeat this 3 times:  
e:-------------------------------------------------------| 
B:---------------------------------------------------3---| 
G:o--------------------------------------------------3--o| 
D:o-------4-------------4-------------4--------------2--o| 
A:---------------------------------------------------3---| 
E:-2--2-2---2--2-2--2-2---2--2-2--2-2---2--2-2--2-2------|  
Repeat this 3 times:  
e:--------------------------|-----------------------------| 
B:-----------------------3--|------------------------3----| 
G:o----------------------3--|------------------------3---o| 
D:o-------4--------------2--|--------4---------------2---o| 
A:-----------------------3--|------------------------3----| 
E:-2--2-2---2--2-2--2-2-----|--2--2-2---2--2-2--2-2-------|  
Then this last part:
e:--------------------------|----------------------------| 
B:-----------------------3--|----------------------------| 
G:-----------------------3--|----------------------------| 
D:--------4--------------2--|--------4-------------------| 
A:-----------------------3--|----------------------------| 
E:-2--2-2---2--2-2--2-2-----|-2--2-2---2--2-2------------|
