Refrain " was the winning song of the Eurovision Song Contest 1956 , co-written by Émile Gardaz and Géo Voumard , performed by Lys Assia representing Switzerland . It was the first-ever winner of the Contest , but not the first-ever performance by Switzerland . This apparent anomaly is due to the rules of the 1956 Contest allowing ( for the only time to date ) each competing country to be represented by '' two '' songs . Assia represented Switzerland singing both songs ( one of only two performers to do this ) , and had previously performed " Das alte Karussell " in German ( " Refrain " was sung in French )
