The later albums "Landed" (1975) and "Flow Motion" (1976) saw Can moving toward a somewhat more conventional style as its recording technology improved. The disco single "I Want More" from "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).
