The Swedish version was released by Fruit Records and MEP in 1997. The English version (renamed R.A.D.) was released in 1998 by Jerusalem Music in the US and Alliance Music in the UK and Europe.Between 1975 and 1983, Ulf Christiansson wrote many songs that Jerusalem never recorded but often played live. After a friend reminded him of these songs and asked why they had never been on an album, Ulf decided to record them, but he wanted to use the band members that were in Jerusalem during the time the songs were actually written.
