First recorded (as “It Must’ve Been Love (Christmas for the Broken Hearted)”) by Roxette (SWE #4 1987).
Hit version by Roxette (US #1/UK #3/CAN #1/AUS #1/NED #3/JPN #2 1990).
From the wiki: “The song, written by Per Gessle, was first released as ‘It Must Have Been Love (Christmas for the Broken Hearted)’ in December 1987. It was composed after EMI Germany asked the duo to ‘come up with an intelligent Christmas single.’ It became a top five hit in Sweden, but was not released internationally. This version of the song was never included on any Roxette studio album until the 1997 re-release of their debut Pearls of Passion.
“A performance from a Swedish TV chart show in 1987 acted as the song’s first music video. It features group members Gessle and Marie Fredriksson sitting on a couch on a stage, lip-syncing to the song.
“During a run of increasingly successful singles from the duo’s 1988 album Look Sharp!, Touchstone Pictures approached Roxette and their label about contributing a song to the soundtrack of the upcoming romantic comedy release Pretty Woman, which was to star Richard Gere and then-Oscar nominee Julia Roberts.
“A re-written and edited version of the track – the lyric ‘It’s a hard Christmas day’ was changed to ‘It’s a hard winter’s day’, twenty seconds were removed from the intro, as well as 24 seconds from the outro – became an international hit during the summer of 1990. It was not the first single released from the Pretty Woman soundtrack, but it became the most successful, spending two weeks at the top spot of the Billboard Hot 100 in June 1990.”
