In 1983, the band released the three-song Shake Up the City EP on Abstract Records, which they also recorded at Jacobs studios. Drummer Kim Wylie played on the EP and for the subsequent tours of the UK, Europe, and the US. They again played several concerts in Poland in 1983 with new wave Polish band Republika . Differences in musical direction, as well as the inability to secure a US record deal, led to Gibbs, Garrett, and Harper going their separate ways, although Harper would continue to use the U.K. Subs name with a frequently-changing line-up of members backing him. The three would reunite for the first time in July 1988 to record Killing Time .
