Trying to remember a particular Jewish song

Hi all, I was wondering if anyone on here could direct me to a particular video I am looking for to help me with an essay I am writing.

I am a high school student that is currently studying Judaism in religion, some time ago my teacher had shown us video footage of a choir of Jewish males singing about the holocaust at this large gathering in a building. From what I can remember it had lyrics in the song that mentioned “erasing the names of the nazis from history” or something similar to that. I remember it was a really powerful and emotional song and I want to use it in a response to an essay we have been given.

Thanks so much!
