1939

J’attendrai (Wikipedia)

Jean Sablon was one of the crooners of the 1930s.  These were difficult years and, ironically, this song was released in 1939.  World War II was about to begin.  After the Anschluss, the annexation of Austria, we had the Sudeten Crisis.  Hitler invaded a part of Czechoslovakia where there was a concentration of German-speaking people.  Then came the invasion of Poland: September 1939.
