This performance makes perfect sense when you read this:

“Nina Hagen was born in the former East Berlin, East Germany, the daughter of Hans Hagen, a scriptwriter, and Eva-Maria Hagen, an actress and singer. Her paternal grandfather died in the Sachsenhausen concentration camp. Her parents divorced when she was two years old, and growing up, she saw her father infrequently. At age four, she began to study ballet, and was considered an opera prodigy by the time she was nine. (Wikipedia)”
