Thank you for all this great information.
The song Eli, Eli, as sung in Yiddish by Connie Francis
is very good, although I consider the audio recording quality
as poor. Another song, also by chance called Eli,Eli, about
Hannah Schennes(?) who parachuted into occupied nazi
territory during the holocaust period to save jews, is a very
nice song in hebrew. I once bought an LP by Israeli actor
TOPOL, and he included that song in the LP.
So there are two songs called ELI,ELI, which could be considered
as songs in memory of the holocaust.
