Baccara was a Spanish female vocal duo formed in 1977 by Spanish artists Mayte Mateos (born 7 February 1951) and María Mendiola (4 April 1952 – 11 September 2021). 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 group, 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.
