The following year, Spain entered Serrat in the Eurovision Song Contest 1968 to sing "La, la, la", but he asked to sing it in Catalan, to which the Spanish authorities would not agree. This would be the first time he would come into conflict with the language politics of Francoist Spain, because of his decision to sing in his native Catalan language, repressed by dictator Francisco Franco. Defiantly, Serrat refused to sing the Spanish-language version, and was hurriedly replaced by Massiel, who went on to win the contest with her Spanish-language interpretation.
