<P> In the 1980s, the song was heard for the first time in a Swedish radio programme featuring ABBA's engineer Michael B. Tretow, and subsequently found its way onto a bootleg album . </P> <P> In 1994, "Dream World" was released in Sweden, Germany and Australia as a promotional - only CD - single with other ABBA rarities to advertise the Thank You for the Music box set, which also contained the track . </P> <P> The version of the song released in 1994 differs from the version heard in the radio show in that its fairground - like synthesiser introduction fades in rather than starting abruptly . However, this is because the tape from which the track was taken was partly destroyed . The "Deluxe Edition" of the Voulez - Vous album (released in May 2010), contains the track with its original beginning . It is unknown how the full introduction was resurrected from the partially destroyed tape . </P> <P> It was reported just before its 1994 release that Benny and Björn were in the studio remixing the track, and hence it is most probably a new mix - down of the song done expressly in 1994 . Indeed, it exhibits a certain "digital" sound suggesting it was mixed down to a digital recorder as opposed to previously released songs from this period which were mixed onto analog tape . </P>
