I am familiar with Jean Ritchie's version but not a longer one. I wrote a simple chorus to the song, which I am planning on recording. (assume key of C):

-------F--------C----------G7----------------------C---
We're orphans, orphans. Drifting this world all alone.
-------F--------C-----------G7------------------C---
We're orphans, orphans. No mama, no papa, nor home.
