The news of the death of one of punk's icons - X-ray Spex's Poly Styrene - is a sad loss. But by way of tribute here she is (and they are) at their melodic best with Germ Free Adolesence:
X-ray Spex's other hits included the Lib Dem poster team fantasy 'Day the world turned day-glo', 'Identity' and 'Oh! Bondage up yours!' all of which are readily viewable on YouTube. I'd heartily recommend doing so as a reminder of the freshness and energy of punk at its pomp.
