Love the defining era singles, I read earlier that Hugh Cornwell left because he thought they were a spent force. I can't say I'm aware of any of their subsequent material but his solo career wasn't anything special so I guess his assessment was wrong, though most acts of that era recorded duff albums anyway (and usually split).
Their peers always had them down as dirty rockers with a keyboard stack rather than punk and the material was derided as sexist, yet to some extent they probably had more fans over a longer period than The Clash or the Pistols among your Average Joe (same with The Jam, also a Surrey band rather than a London one).
