Turner was later replaced by Sean Oliver (later of Rip, Rig & Panic) on bass.

They then released a self-titled EP on Virgin Records in 1979, before signing to Rough Trade.

Between 1978 and 1981, Logic also performed as a member of Red Crayola,[1] as well as playing on recordings by Kollaa Kestää, The Stranglers, The Raincoats and Swell Maps.

Soon after Pedigree Charm was released in 1982 on the Rough Trade label,[1] Logic gave up recording and performing: she had turned to the Hare Krishna religion.

She resumed Essential Logic in 2001 with a new line-up, and released a four-track EP of new material.
