Here's the rewrite of Dreadful Wind and Rain/Two Sisters that I'm working on for anyone with any interest (and here is the Garcia/Grisman version I adapted from):

A knight gave a maiden a golden ring
oh the wind and rain
Didn't give her younger sister anything
cryin' oh the dreadful wind and rain

The two sisters walked along a forest stream
oh the wind and rain
The young one pushed the older one in
cryin' oh the dreadful wind and rain

Into the deepest water to drown
oh the wind and rain
Watched her as she floated down
cryin' oh the dreadful wind and rain

The water took her down to the miller's pond
oh the wind and rain
His young daughter said there swims a swan
cryin' oh the dreadful wind and rain

The miller pulled the corpse with a long pole hook
oh the wind and rain
Drew the dead maiden out from the brook
cryin' oh the dreadful wind and rain

He left her on the shore in the sun to dry
cryin' oh the wind and rain
A banjo maker came a passing by
cryin' oh the dreadful wind and rain

Gathered her body and took it to his home
oh the wind and rain
Took all the flesh from off her bones
cryin' oh the dreadful wind and rain

Made a banjo head from her fair skin
oh the wind and rain
Made a banjo head from her fair skin
cryin’ oh the dreadful wind and rain

Made 5 strings from her golden hair
oh the wind and rain
Made 5 strings from her golden hair
cryin' oh the dreadful wind and rain

Made tuning pegs of her long finger bones
oh the wind and rain
Made tuning pegs of her long finger bones
cryin' oh the dreadful wind and rain

Only song that the banjo ever would play
was oh the wind and rain
The only song that the banjo ever played
was oh the dreadful wind and rain
