It was released as a single in 1999, reaching the #6 position on the UK Singles Chart and becoming a popular dance track in clubs across Europe. In 2003 the song was used in a national tourism campaign for Ireland and also by Belfast City Council in adverts promoting the city.
The "Saltwater" music video, incorporating images of surfing juxtaposed with the frenzy of a nightclub, was filmed in February 1999. The surfing scenes were shot in Woolacombe, North Devon, the location of many beaches that are popular surfer destinations. The club scenes were shot at a studio on Old Street in London as well at the actual Gatecrasher club in Sheffield.
