The ballad became the duo's third number one hit in the United States, and is one of their best selling releases, being certified gold or platinum in a number of countries.
Four different versions of the song have been officially released.
The original 1987 track was followed by the most successful incarnation of the song, a slightly edited version - omitting the Christmas references - which was created for the soundtrack to the 1990 movie Pretty Woman.
A performance from a Swedish TV chart show in 1987 acted as the song's first music video. It features Fredriksson and Gessle sitting on a couch on a stage, lip-syncing to the song.
The song was certified Gold by the RIAA for sales in excess of 500,000 copies in the US.
