EDIT: My dad wrote an explanation of the three songs in this video:
There are three songs on the video. The first is “Ich hatt’ einen Kameraden” which is traditionally played whenever a German soldier dies. The second is “Nach Meiner Heimat“, a song about going back to your hometown.
The third song was especially sentimental to Dad. “Antje Mein Blondes Kind” was the song that saved his life in WWII and he would tear up every time he heard it. Dad was in a bombed out building in Italy on the ground floor trying to contact the base with a field radio transmitter. There were several other soldiers of his battalion on the second floor keeping lookout when “Antje Mein Blondes Kind” came on their shortwave radio. They called for Dad to come up and listen to it but Dad insisted on continuing to make contact with base. The guys yelled down that the song would soon be over and for Dad to hurry upstairs. Dad was annoyed at their constant interruptions and finally took off his headphones and proceeded to go up the stairs. About half way up the stairs, a bomb hit the corner where his field radio was. The enemy had triangulated the transmission signals and bombed the radio location.
I still love and miss you, Opa.
