Marke sung all six songs in the 1965 Eurovision selection, and "Als het weer lente is" ("When It's Spring Again") was chosen by jury vote as the Belgian representative in the tenth Eurovision Song Contest, held on 20 March in Naples, Italy. "Als het weer lente is" failed to score, finishing in joint last place (with Finland, Germany and Spain) of the 18 entrants. It was Belgium's second "nul pointer", following Fud Leclerc's zero in 1962. Marke was the first female singer to represent Belgium at Eurovision since Mony Marc in the inaugural contest of 1956.
