Written for the Swedish movie Inga II, the song was recorded in November/December 1969, most likely at Europa Film Studios. The song was originally released in March 1970 as the first Björn and Benny single. Two years later it was released in Japan, hitting #1 and selling half a million copies.
The song was subsequently put on the B-side of the Swedish issue of ABBA's Ring Ring (English version) single, and on the "Ring Ring" album in some other countries (in spite of it having been recorded before ABBA was formed and featuring no contribution from ABBA's other members, Agnetha Fältskog and Anni-Frid Lyngstad).
This song was used in the soft porn film "Inga II : The Seduction of Inga" in 1971 (directed by Joseph W. Sarno), along with the song "Inga's Theme". This film was released in the U.S and Sweden, but became a bigger smash in the U.S.
