Both singers had previous experience of performing in the Eurovision Song Contest with Hanne representing Norway in 1971 and Elisabeth representing Sweden as part of the group Chips in 1982. Bobbysocks' victory in 1985 was a breakthrough for Norway in the song contest, the significance of which was not lost on the host Lil Lindfors who remarked "I'm honestly very happy that this happened, because Norway has been last so many times that you really deserve it!"

Hanne Krogh returned to the Eurovision Song Contest in 1991 representing Norway again as part of the group Just 4 Fun. Elisabeth Andreassen returned to the contest in 1994 duetting with the singer Jan Werner Danielsen. She also represented Norway on home ground in 1996 finishing second behind Ireland. In 1998 Elisabeth entered Melodi Grand Prix finishing second with Winds of the Northern Seas. More recently the duo performed together at Eurovision's Greatest Hits, a celebration of the 60th anniversary of the Eurovision Song Contest.
