"Yes Sir, I Can Boogie" is the biggest hit of the Spanish duo Baccara (formed by Mayte Mateos and María Mendiola). They worked as singers and dancers in a hotel in the Canary Islands when German producer Rolf Soja heard them and composed the music especially for them in 1977. Released as the first single of their career, the track reached #1 in the United Kingdom (being the first Spanish artists to achieve this), #1 in several other countries of the continent and sold more than 16 million copies worldwide. With its danceable groove, addictive chorus and glamorous look, the song became one of the biggest Eurodisco hits of the 70s.
