"Chan Chan" is a 1984 son composition by Cuban trovador Compay Segundo. It was first recorded in 1985 by Compay Segundo's own group. In 1987, he approached Eliades Ochoa, who agreed to record a version with the Cuarteto Patria. However, EGREM did not release these recordings until the second half of the 1990s. In November 1995, Compay recorded a new version in Madrid for his Antología, released on CD the following year. From Wikipedia
