Charged GBH, commonly known as GBH, are an English street punk band which was formed in 1978 by vocalist Colin Abrahall, guitarist Colin "Jock" Blyth, bassist Sean McCarthy and Drummer Andy "Wilf" Williams. GBH were early pioneers of English street punk, often nicknamed "UK82", along with Discharge, Broken Bones, The Exploited and The Varukers. They have gone on to influence several punk rock musicians. The name GBH was inspired by then-bassist Sean McCarthy's trial for grievous bodily harm, though some fans also believe it is an acronym for "Great Britain Hardcore".
