Question re final song sung by Mrs. Kubrick

Rating: Null/10 (23 June 2006)

During a recent showing of "Paths of Glory" at the National Arts Club in NYC, a question was raised regarding the lyrics and the title of the song sung in the final scene (in the bar) by the young German girl (Mrs. Kubrick). Obviously, Kubrick has always made effective use of music in all his films--"We'll Meet Again" in the last scene of "Doctor Strangelove," "Singing in the Rain" in "A Clockwork Orange," "Thus Spake Zarathusa" at the beginning of "2001." During the opening credits of "Paths of Glory," we hear the French National Anthem. Apparently Kubrick wanted "to frame" the film with a French melody at the beginning and a German tune at the end. Unfortunately no one in the audience on June 22 knew enough German to translate or name the song. Can anyone supply me with the title of the song and an English translation of the German words that so move the rowdy French soldiers?
