In 1971, Mendt was chosen by broadcaster ORF to represent Austria with the song "Musik" in the 16th Eurovision Song Contest, held in Dublin on 3 April. It marked Austria's return to Eurovision following a two-year absence. "Musik" – the only song performed at Eurovision to date in the Viennese German dialect – was drawn as the show's opening song, and at the end of voting could only manage 16th place of the 18 entries, after a somewhat nervous and hesitant performance from Mendt.
