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 nine singles in history to have sold over 15 million copies worldwide. It is currently eighth on the list of best-selling singles of all time, with an estimated total of 18 million units.
