Looking for yiddish song

Hi,

I’m hoping people here can help me. I recently heard a beautiful song in yiddish, but have no idea who sings it (it was a child) or where I can find the song. The lyrics are quite haunting, it starts with a mother in Aushwitz who watches her small son being taken to be burnt, and she asks him to go up to the kisei hakavod and ask rachamim from Hashem on Am Yisroel. The song then continues how through all the thousands of years of golus, we never stopped saying Shma Yisroel.

Does anyone know this song?

Thanks in advance!
