Baccara

Baccara was a Spanish female vocal duo formed in 1977 by Spanish artists María Mendiola (4 April 1952 – 11 September 2021) and Mayte Mateos (born 7 February 1951). The duo rapidly achieved international success with their debut single "Yes Sir, I Can Boogie", which reached number one across much of Europe and became the best-selling single of all time by a female duo, eventually selling more than 16 million copies worldwide. A successful follow-up single ("Sorry, I'm a Lady") and European tour led to a number of album releases, numerous television appearances and the duo's selection to represent Luxembourg in the Eurovision Song Contest 1978. Despite a substantial following in Spain, Germany and Japan, by 1981 their blend of disco, pop and Spanish folk music was no longer fashionable, and by 1983 Mateos and Mendiola were both working on solo projects.
