Flow Motion became its only hit record outside Germany. Co-written by live sound mixer Peter Gilmour, it reached No 26 in the UK charts in October 1976, which prompted an appearance on Top of the Pops, where Czukay performed with a double bass. In 1977 Can was joined by former Traffic bassist Rosko Gee and percussionist Rebop Kwaku Baah, both of whom provided vocals, appearing on the albums Saw Delight (1977), Out of Reach (1978) and Can (1979). During this period Czukay was pushed to the fringes of the group's activity due to disagreements about the band's creative direction and his failure as a bass guitarist to keep up with the growth of the other musicians. Bass guitar was something Czukay had "taken up almost by default" and he readily admitted his limitations on the instrument. After Gee joined Can, Czukay made sounds using shortwave radios, Morse code keys, tape recorders and other sundry objects. He left Can in late 1977 and did not appear on the albums Out of Reach or Can, although he was involved with production work for the latter album. The band seemed to be in a hiatus shortly afterwards, but reunions have taken place on several occasions since. After the split and reunion Since the split, all the former members have been involved in musical projects, often as session musicians for other artists. In 1986 they briefly reformed, with original vocalist Mooney, to record Rite Time (released in 1989). There was a further reunion in 1991 by Karoli, Liebezeit, Mooney and Schmidt to record a track for the Wim Wenders film Until the End of the World and in August 1999 by Karoli, Liebezeit and Schmidt with Jono Podmore to record a cover of "The Third Man Theme" for Grönland Records' compilation album Pop 2000. In 1999 the four core members of Can, Karoli, Liebezeit, Schmidt and Czukay, performed live at the same show, although playing separately with their current solo projects (Sofortkontakt, Club Off Chaos, Kumo and U-She respectively). Can have since been the subject of numerous compilations, live albums and samples. In 2004, the band began a series of Super Audio CD remasters of its back catalog, which were finished in 2006. Michael Karoli died of cancer on 17 November 2001; Jaki Liebezeit died of pneumonia on 22 January 2017, and Czukay died of natural causes on 5 September 2017, thus leaving Irmin
