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.
