Black Rain

a
E|------------------------------------------------------| 
B|------------------------------------------------------| 
G|--------0------------0-----------0--------------------| 
D|------4---4--------4---4-------4---4------------------| 
A|---2--------2----2-------2---2-------2----------------| 
E|-0-------------0-----------0--------------------------| 

Then it changes to:
b
E|------------------------------------------------------| 
B|------------------------------------------------------| 
G|--------0------------0-----------0--------------------| 
D|------4---4--------4---4-------4---4------------------| 
A|---2--------2----2-------2---2-------2----------------| 
E|-3-------------3-----------3--------------------------| 

Like I said before, I'm not sure of the changes but it goes back and forth several times in the 
song

After playing through a and b several times switch to:
c
E|------------------------------------------------------| 
B|-------0-----------0-----------0----------------------| 
G|-----4---4-------4---4-------4---4--------------------| 
D|---2-------2---2-------2---2-------2------------------| 
A|-0-----------0-----------0----------------------------| 
E|------------------------------------------------------| 

d
E|------------------------------------------------------| 
B|-------0-----------0-----------0----------------------| 
G|-----4---4-------4---4-------4---4--------------------| 
D|---2-------2---2-------2---2-------2------------------| 
A|-3-----------3-----------3----------------------------| 
E|------------------------------------------------------| 

The song goes back to play a and b several times and back to c and d and back to a and b again.
