International Year of the Child International Year of the Child UNESCO proclaimed 1979 as the International Year of the Child. The proclamation was signed on January 1, 1979 by United Nations Secretary General Kurt Waldheim. A follow-up to the 1959 Declaration of the Rights of the Child, the proclamation was intended to draw attention to problems that affected children throughout the world, including malnutrition and lack of access to education. Many of these efforts resulted in the Convention on the Rights of the Child in 1989. Numerous events took place within the UN and in member countries to mark the event, including the Music for
ABBA countries as well as in Japan and Australia. The album became a major success, and along with the Spanish version of "Chiquitita", this signalled the group's breakthrough in Latin America. "ABBA Oro: Grandes Éxitos", the Spanish equivalent of "ABBA Gold: Greatest Hits", was released in 1999. In January 1981, Ulvaeus married Lena Källersjö, and manager Stig Anderson celebrated his 50th birthday with a party. For this occasion, ABBA recorded the track "Hovas Vittne" (a pun on the Swedish name for Jehovah's Witness and Anderson's birthplace, Hova) as a tribute to him, and released it only on 200 red vinyl copies,
