Golfer,
It seems I thought it was more well known. In very short, it’s a song called Ani Ba’yaar holachti. And the version I know, was sung by Rav Yaacov Salzer Zt”l in Johannesburg. The story is about someone walking in the forest and heard a peasant calling his/her daughter, Katerina, young lady,come here. In that language it’s “Katerina, maleditza, podusodoy” or something like that. So the song is understanding those words to mean that Hashem will come and redeem His people and we will all sing together.
Kat is a group
Rina is song
Male is full
Ditza is joy
Poide is redeem
Sodoy is the shem Shin, dalet and yud.
I’m sure it’s available on the popular search engines…
