What is "mocedades"

Mocedades is a Spanish singing group from the Basque Country, who represented Spain in the Eurovision Song Contest in 1973 with the hit song " Eres Tú". Since June 2014, Mocedades has been the name of two bands: one with Izaskun Uranga as its leader and the other with Javier Garay. A third group, El Consorcio, is composed of former Mocedades members who left the group but have continued a career together outside the Mocedades brand.
