Spanish flamenco artists Mayte Mateus and Maria Mendiolo were already performing together in 1977 for tourists when they were snapped up by RCA exec Leon Deane. Named Baccara, the duo partnered with Rolf Soja, who penned their debut, "Yes Sir I Can Boogie." Released in the middle of 1977, the song rocketed up the U.K. charts, scoring the band a number one in September. On the strength of that song, their self-titled debut album was an instant success, and a further follow-up single, "Sorry I'm a Lady," gave the duo another U.K. hit in early 1978. Touring Europe brought Baccara a larger fan base and even wider audience for their follow-up albums. Light My Fire was released in 1978 and spun off several singles, including "La Bamba" and "Parlez-Vous Franšais?" The latter, of course, was their entry for that year's Eurovision Song Contest, where they represented Luxembourg. A hot property, Baccara found themselves on the European and U.K. television circuit, appearing on Germany's Musikladen and on England's Sacha Distel Show as regular guests while their disco was in fashion.
