Francisco '' ' Javier Garay ' '' Barrenechea is a member of the Spanish vocal group Mocedades , singing tenor and playing guitar , and is one of the so-called " historic six " members of the group . Although Garay did work with the group during its inception in 1967/8 , when it was known as Voces y Guitarras , he had to leave to complete his compulsory military service and did not become an official member of the group until 1970 . In 1973 Mocedades represented Spain in the Eurovision Song Competition in Luxembourg where they came in second place with the song " Eres Tú " . The song became an international hit and marked the beginning of the group 's most successful period . The member line-up during this period is known as the " historic six " which remained the same until 1985 with the departure of lead singer Amaya Uranga . Since then the group has had several changes in personnel , but Garay stayed with the group and he and Izaskun Uranga are the only two remaining members of the " historic six " still in Mocedades . Although most of Mocedades ' songs have a female singer on lead vocals , Garay gradually emerged as the leading male voice with several solos including the hits " Le Llamaban Loca " and " Sobreviviremos " , among others . He is the main spokesman for the group and communicates regularly with fans through the official online forum
