On stage: Joachim Vogel (rhythm guitar), Jeanne Dupuy and Frank Otto (drums), Nadja Abd el Farrag (vocals).[clarification needed] In 1988 Frank Otto was replaced by Michel Rollin. After that in 1991 a new keyboardist joined for live shows – Achim Strieben. In TV shows and videos he was replaced by Friedrich Graner (Sir Fritz), who remained a part of the group until the break-up in 1998. In 1992 Dirk Sauer, Rene Engelman and Wolfgang Fritsch joined the group, while Joachim Vogel left.
Some of the group's singles such as "Sorry, Little Sarah" or "My Bed Is Too Big" achieved moderate success in Europe. The group released 22 video clips from their album repertoire and most of these were aired in Europe, especially on German TV shows. Blue System also had several concert performances in Russia[citation needed] during the late 80s and early 90s.
