The album 'Copacabana' by Sarah Vaughan was released in 1979, although there is no widely verified information about its recording, producer, or record label in standard reliable sources.
It is believed that this record may have been a studio production aimed at the Latin American market or a live recording, but no confirmed data supports this theory.
Due to the lack of historical documentation, this album is considered a rarity in Vaughan's discography, and its existence is mainly mentioned in unofficial listings.
