Here's the English lyrics to the Chorus part represented on our sheet music.
"Bei mir bistu shein, please let me explain,
Bei mir bistu shein, again I'll explain,
It means you're the fairest in the land.
Each language only helps me tell you
How grand you are.
I've tried to explain "Bei mir bistu shein".
So kiss me and say you understand."
