In 1965, she represented Germany in the Eurovision Song Contest, with "Paradies, wo bist du?"
Other than the Eurovision Song Contest, where her zero-point result hurt her solo career before it had even fully begun,[1] she was mainly active with the Botho-Lucas-Chorus, where she stayed as chorister for 30 years,[2] notable for their musical accompaniment on the German TV show Musik ist Trumpf.
Wiesner released an album called Twilight Mood in 1970 with Addy Flor and his Orchestra.
As one of Germany's busiest studio singers, she was assigned as backing vocalist for many popular artists, including Triumvirat's album Illusions on a Double Dimple in 1974.
[5][6] Wiesner married the German TV producer and personality Alexander Arnz (1932–2004) in 1999.
