Baccara were a very popular Spanish dance-pop duo in the late seventies. The group consisted of Mayte Mateus (7 March 1951), and María Mendiola (4 May 1952). Their music was a blend of pop and disco, with lyrics in English sung with the peculiar Spanish accent of the two singers. Baccara's most famous hits were "Sorry I'm a lady" and "Yes sir, I can boogie", both of which topped the charts during 1977 in some European countries, including the United Kingdom.
