I don?t feel like writing the how many but these are 
the 3 chords throughout the song

E------------------------------------------------------
B------------------------------------------------------
G-------------5----------------------------------------
D----3----2---5----------------------------------------
A--- 3----2---3----------------------------------------
E----1----0--------------------------------------------


If you want to have a lead guitar do something neat 
that will go well on the B string hit the 12th fret 8
and then the 13th fret 8 times and repeat
