In 1981, Swedish music promoter Bert Karlsson met then 15-year-old Häggkvist after she performed on the television series "Hylands hörna" and offered her the chance to take part in "Melodifestivalen", the Swedish selection for the Eurovision Song Contest in 1982. She turned down the offer. Songwriter Lasse Holm offered Häggkvist two of his songs for Melodifestivalen 1983, "Mona Lisa" and "Främling". "Främling" was chosen, and with it Häggkvist won the right to represent Sweden at that year's Eurovision Song Contest in Munich. The song scored eight points, the highest possible mark, from all eleven regional juries. Häggkvist represented Sweden at the Eurovision Song Contest on 23 April. She finished third in front of 6.1 million Swedish television viewers, 84% of the country's population. This is still a record in Sweden.
