Chiquitita

ABBA were finishing work on Voulez-Vous, their sixth studio album, when "Chiquitita" became one of the last tracks recorded for the record. The song went through several working titles, including "Kålsupare", "3 Wise Guys", "Chiquitita Angelina" and "In the Arms of Rosalita". A revised version, influenced by the Peruvian song "El Condor Pasa (If I Could)" performed by Simon and Garfunkel, was recorded in December 1978. Agnetha Fältskog sang lead vocals, performing alone for roughly the first minute before Anni-Frid Lyngstad joined her in harmony for the remainder. Although "If It Wasn't for the Nights" had been planned as the lead single, it was scrapped once "Chiquitita" was completed. Polar Music released the track on 16 January 1979, with the non-album song "Lovelight" on the B-side.

The group debuted the single at the Music for UNICEF Concert, broadcast worldwide from the United Nations General Assembly, and afterwards donated 50 percent of all royalties to UNICEF in recognition of the International Year of the Child. The single reached number one in Belgium, Finland, Ireland, the Netherlands, New Zealand, Portugal and Switzerland, while peaking at number two in the United Kingdom, where Blondie's "Heart of Glass" held the top spot. It was the first ABBA lead single since "So Long" to miss the top position there, though it reached number one on the NME chart.

RCA Records, the band's label in much of South America, suggested recording one of their hits in Spanish, an idea put forward by employee Buddy McCluskey. He and his wife Mary wrote the Spanish lyrics, and the version was released in Argentina in April 1979. It sold more than 2.5 million copies across Latin America and Spain, where it topped the Superventas chart in May 1979.
