This is my first tab. Really fun song. I have seen videos of Amos and this is how he 
it. Listen to the song for the rhythm.

Verses:

D
He got a new mercy, a new grace
C
Street corner preacher with the angry face
G

Same for the ba ba ba part

           C           G           D
There's a whole lotta trouble all around
C                G              D
Every night the same old siren sound...
