Past the Eurovision Song Contest, of which the zero point result has hurt her solo career before it even fully began, she was mainly active as chorister, firstly at the Günter-Kallmann-Chorus and later on at the very famous Botho-Lucas-Chorus, where she stayed as chorister as main profession for 30 years, notably for their musical accompaniment on the German TV show "Musik ist Trumpf". Together with Addy Flor and his Orchestra, Ulla Wiesner released an album called "Twilight Mood" in 1970. As one of Germany's busiest studio singers, she was assigned as backing vocalist for many popoular artists, including Triumvirats album "Illusions on a Double Dimple".
Since then, notable singles of hers include titles such as "Abends kommen die Sterne" (In the evening the stars appear), "Wenn dieser Tag zu Ende geht" (When this day comes to an end) and "Charade".
Wiesner married the German TV producer and personality Alexander Arnz (1932–2004) in 1999 with whom she has had 2 sons. She retired from the music industry in 2002.
