[5] Notes The pre-ABBA songs "Hej Gamle Man", "Tänk Om Jorden Vore Ung", "She's My Kind of Girl", "Det Kan Ingen Doktor Hjälpa", "En karusell/En Carousel" and "Love Has Its Ways" were released in Sweden and/or Japan as singles (1970–1972).

These songs were released officially as singles by Björn & Benny, but some featured vocal contributions from both Agnetha Fältskog and Anni-Frid Lyngstad.

"En hälsning till våra parkarrangörer" was released as a promo single (1972) in order promote ABBA's then-upcoming tour of the Swedish "Folk Parks".

This track was in fact a series of snippets of then well-known ABBA-songs and solo-songs with a spoken overdub featuring all of the ABBA-members.

The videos were successful, and the following year the group rehired him to make four promo clips of the songs they felt had the strongest hit potential on the new album ("I Do, I Do, I Do, I Do, I Do", "Mamma Mia", "SOS" and "Bang-A-Boomerang").

The relationship ended in 1982, prompted by changing tastes and demands and complaints from ABBA's distributors that Hallström's low-budget approach made it difficult to market the band.

Director Kjell Sundvall and cinematographer Kjell-Åke Andersson, an up-and-coming filmmaker team, were hired to replace them for the final two promotional videos, "The Day Before You Came" and "Under Attack".
