In 1973, she was selected to represent Luxembourg as the Grand Duchy sought to repeat its previous year's triumph on home soil in the Eurovision Song Contest. She thus joined the long list of non-native performers to have represented the country in the contest, which also includes France Gall (the 1965 winner) and Vicky Leandros (the 1972 winner). The 1973 contest crystallised into a three-way battle between songs that have since established themselves as Eurovision classics: David's "Tu te reconnaîtras", the Spanish entry "Eres tú", and the United Kingdom's "Power to All Our Friends", performed by Cliff Richard. Ultimately six points separated the third place from David, securing the second successive triumph for Luxembourg.
