for the song is sometimes also attributed to Joseíto Fernández, who claimed to have written it at various dates (consensus puts 1929 as its year of origin), and who used it regularly in one of his radio programs. Some claim that the song's structure actually came from Herminio "El Diablo" García Wilson, who could be credited as a co-composer. García's heirs took the matter to court decades later, but lost the case; the People's Supreme Court of Cuba credited Fernández as the sole composer of the music in 1993. Regardless of either claim, Fernández can safely be claimed as being the first to promote the song widely through his radio programs. Pete Seeger version Shortly after the Weavers’ Carnegie Hall reunion concert recording in May 1963, Pete Seeger included the song on his album We Shall Overcome, which was also performed live at Carnegie Hall. Seeger's recording is described by Stewart Mason at Allmusic as the "definitive version" of the song. The version of the song created by Martí and Orbón was used by Seeger as the basis of his reworked version, which he based on a performance of the song by Héctor Angulo. Seeger combined Martí's verse with the tune, with the intention that it be used by the peace movement at the time of the Cuban Missile Crisis. He urged that people sing the song as a symbol of unity between the American and Cuban peoples, and called for it to be sung in Spanish to "hasten the day [that] the USA... is some sort of bilingual country." The Sandpipers version The most commercially successful version of "Guantanamera" in the English-speaking world was recorded by the easy listening vocal group, The Sandpipers, in 1966. Their recording was based on the Weavers' 1963 Carnegie Hall reunion concert rendition and was arranged by Mort Garson and produced by Tommy LiPuma. In addition to the group's vocals, the version includes Robie Lester on background vocals and narration by producer LiPuma. It reached No. 9 on the Billboard Hot 100 and No. 7 on the UK Singles Chart.
