 This concert of Mocedades features their greatest hits because of their 15th anniversary as a group. It was held in the Alcala Palace Theatre in February 1984. Sergio & Estíbaliz, ex-members of the group, joined them on this occasion singing three songs with them. The orchestra was directed by Juan Carlos Calderón during the first half of the concert, composer and producer of many of their songs and Graham Preskett during the second half, producer for the Sony-CBS music albums.
