They released another single, called "Crack Attack", first a fairly noisy, grungy (in a pre-Nirvana way) version, and then, a year or so later, a cleaned-up version on EMI, with dance mixes and that crap. The earlier version got combined with the Drag Racing 12" on a compilation called Crack 'n' Drag, which, amazingly, is still available through Mute records
