It couldn't have been easier...


Verse:

Gm              F      Gm   
Go son, go down to the water
Gm                F       Gm   
And see the women weeping there....  cont. sim.


Chorus:

F          Gm             F                Gm  
This is a weeping song, a song in which to weep
              F             Gm
while all the men and women sleep
F          Gm                 F                 Gm
This is a weeping song, but I won't be weeping long.


That's about it!
