This is a super easy song. 

G    C     G            Bm         Am 
G    C     G            Bm         Am 

G    C                 G             
     When the revenant     came down  
Bm                             Am  
     We couldn't imagine what it was  
G    C                G 
     In the spirit of      three stars  
Bm                                     Am 
     The alien thing that took its form  
G    D   C                
         Then to Lebanon  
G   
     Oh, God  
Bm                                          Am 
     The flashing at night, the sirens grow and grow  
G    D   C                      G   
         Oh, history involved itself  
Bm                                  Am 
     Mysterious shade that took its form  
G    D      
     Or what it was, incarnation  
G 
Three stars  
Bm                                      Am  
Delivering signs and dusting from their eyes 
G   C   G   D
