The first part of the BBC 4 'Punk Britannia' season from a few weeks back.
Very interesting - focussed on the pub rock scene of the early 70s rather than jumping straight into the Sex Pistols. I recall that scene being covered in the NME etc but, not living in London, it made no impression.
Punk was everything I loathed at the time; but it's not hard to see why it happened.
I'll still not be swapping my King Crimson records for The Clash!
