Hi, Rachel - I have the song listed as "Royte Pomarantsn" (Blood Oranges)

https://music.youtube.com/watch?v=SQWdmcJ373A&list=OLAK5uy_lq1c32ydl1P65LqSkSFv8OJ_jwOYxa0aM

Such Blood Oranges are mentioned in the song "di grine kuzine," but I see no other connection to the Green Cousin. So, I'm coming up zero on this one, too.
I'm so ashamed....

Here's a page that offers a translation of at least part of the song:
https://www.klezmershack.com/bands/bow/royte/bow.royte.html:

"Musicians, don't go easy on the strings! / With friends around you left and right, / and eyes aglow with joy, delight ... no more thinking black and white / just a true and open heart / a beggar and a wanderer no more."
