From Missy Lerner: 

Dear Friends,

To fully appreciate the Jewish refusal to abandon "The Hope" -- or,
in Hebrew, "Hatikva" -- you must listen to this recently-discovered
recording of Jewish prisoners in Bergen Belsen singing Hatikva
on the first Shabbat after hearing of their liberation, April 20, 1945.

The introduction is by the BBC.

Hatikva - English Lyrics
As long as deep in the heart,
The soul of a Jew yearns,
And forward to the East
To Zion, an eye looks
Our hope will not be lost,
The hope of two thousand years,
To be a free nation in our land,
The land of Zion and Jerusalem.
