In 1977, drummer Per-Anders Carlsson left the band as he felt the success had outgrown him, and he was replaced by experienced drummer Anders Erixon, who had been the band's drummer in the late sixties. The year after, the band recorded an English-language album titled "Export" as an attempt to receive international recognition but without success. Later that year, just as the band was finishing yet another tour following their latest album, "Kramgoa Låtar 6", lead singer Stefan Borsch announced his departure to focus on a solo career. This came as a shock to the band, who were having greater success than ever at the time. Borsch would later state in interviews that he regretted leaving the band at that point, and several times considered going back in the following years. Hired to replace him was Christer Sjögren, a skilled yet unknown vocalist, who would stay as the band's singer for the rest of their career. The band soon recorded and released their ninth album, "Kramgoa Låtar 7", including a Swedish cover of "Dschingis Kahn", the West German entry to the Eurovision Song Contest in 1979. In 1980, bass guitarist Börje Gunnarsson left the band, and was replaced with Lars-Åke Svantesson, who in addition to playing the bass guitar, would co-produce the band's albums for the next eight years.
