As far as I can tell is Bflat->Dm->F#m->Dm

Bflat                      Dm
I walk down these city streets
                      Gm
Just a lonely man inspired
                                  Dm
Hoping God will send me water down  To quench this burning fire

Bflat                      Dm
If i left here for the mountain
               Gm
A monastery man
                                       Dm
Things will stay the same so I'll remain And show just who I am

Seeing things around me
Bonnie and Clyde
Graffiti with no message
Doctors, medicines, or pride

But it doesn't really matter
They're blowin' in the wind
On the cover of a magazine

----Chorus----
    repeat X2

Hallelujah
Babylon is falling
Babylon is falling

----2nd verse----

I try to wash my dirty hands
But they won't come off the water
Hopin' truth will make me clean and then
Redeem my sons and daughters

Though they're not yet on the very highway
Pass along below
That's why I left my memories far behind the lazy road

Seems so simple
Future's the past
The present are the things we holdin' on to make them last

But it doesn't really matter
Blowin in the wind
With they’re head high

There might be another chord at the end of each versus that not in the tab,  The tab is 
pretty much the same as the other one in here except for the Gm chord that I thought was missing.
