In 1968, he won the Benidorm International Song Festival, a songwriter's event in Spain, with the song "La vida sigue igual" (meaning "Life Goes On The Same") which was used in the film La vida sigue igual about his own life. He then signed a deal with Discos Columbia, the Spanish branch of the Columbia Records company, and released his first studio album, titled Yo Canto, or I Sing. The album spent 15 weeks in the Spanish charts and peaked at #3. He represented Spain in the 1970 Eurovision Song Contest, finishing in fourth place behind Ireland's winning entry, performed by Dana. His entry was the song "Gwendolyne." Shortly after, he had a number one hit in many European countries with "Un Canto A Galicia", sung in Galician, in honour of his father, who hailed from Galicia. That single sold 1 million copies in Germany. In 1975, he found success in the Italian market by recording a song exclusively in Italian, called "Se mi lasci non vale" or "If You Leave Me, It Can't Be." Notable albums from this decade are A flor de piel (1974, with the European hit "Manuela"), El amor (1975), and Soy (1973). He also sang in French: one of his popular songs in this language became "Je n'ai pas changé."
