McFarlane and Campsie originally met in California in 1978, and began working together when they returned to England, taking the name "The Quick". Their debut single, "Sharks Are Cool, Jets Are Hot," was released on Epic Records in 1979. In 1981, the duo's single, "Hip Shake Jerk," became a hit in Australia, reaching #12, and their first album, On the Uptake was quickly released there. Remixed and repackaged as "One Light in a Blackout" (in Canada) and "Fascinating Rhythm" (in Europe), the album was released to the rest of the world in 1982, spawning a U.S. dance hit, "Zulu". The single "Rhythm of the Jungle" was another Top 20 success in Australia, reaching #13, and also became a hit in Europe. A second album, International Thing, followed in 1984.
By that time, McFarlane and Campsie had started doing studio work for other musicians, producing an album for Endgames among others. Their last album, Wah Wah, came out in 1986 on A&M Records. McFarlane and Campsie would resurface as Giant Steps in 1988. Campsie is married to Beverley Craven.
