"Yes Sir, I Can Boogie" is a 1977 hit single by the Spanish vocal duo Baccara.
Written by Frank Dostal and Rolf Soja, and produced by Soja, this standard disco song was a major hit across Europe and became the duo's sole number one single in the UK, spending a single week at the top in October 1977. It did not chart in the United States, despite receiving airplay in several markets. It is one of the fewer than 10 all-time singles to have sold 15 million (or more) copies worldwide, currently being #7 on the list of best-selling singles of all time, with an estimated total of 18 million. Baccara were Spanish flamenco dancers Mayte Mateos and Maria Mendiola, who were dancing flamenco and singing traditional songs for tourists on the island of Fuerteventura when RCA Records executive Leon Deane signed them up.
