I really hadn’t meant to write a postscript to last week’s column on my dark Supertramp past. But then along came a TV programme which reminded me: I WAS cool once. It happened after Oxford when I became, almost simultaneously, both an acid-house freak and an indie kid. And BBC4’s three-part special — Music For Misfits: The Story of Indie (Friday) — captured quite brilliantly what it was like to live in that golden era of floppy fringes, black Levis, obscure music, psychotropic substances and DM boots.
