Looking back to punk and post punk days, I find it hard to understand why it made me feel old at first. I had grown up on Zeppelin, Hendrix, Dylan, Clapton, Bowie and all the usual suspects. The vanguard of punk tried to blow all the old farts away, but looking back I realise that most of them (Lydon, Devoto, Shelley, even Ian Curtis) were the same age as me give or take a year (I'm 52 now), Strummer even older, so why did I suddenly feel that I belonged to an earlier generation? What had they grown up listening to?
