I got a note from Len Wallace. He thanks us all for our help. He thinks "Zog nit kein'mol" was the one he wanted.
See this thread for French partisan songs.
Here's Len's message:
Many, many thanks for the responses for lyrics to Jewish Partisan songs.
I think i found the right one with "Zog nit kein'mol". Very much appreciate all of you answering me.
For music that never dies,
