Baccara was a female vocal uo formed in 1977 by Spanish flamenco artists Mayte Mateos (February 7, 1951, Logroño) and María Mendiola (April 4, 1952, Madrid). The pair rapidly achieved international success with their debut single "Yes Sir, I Can Boogie", which reached number one across much of Europe. 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 in 1978.
