Out of shot

The chances of pretty much any gig going unrecorded for posterity these days are extremely slim. But it certainly happened in the past - meaning that, for some legendary, infamous and/or crucially significant shows (Marc Bolan at Glastonbury in 1970, live debuts for the Sex Pistols and Radiohead, The Who's near-residency at the Marquee Club in 1965), all that remains are the memories. Unless you've got photos tucked away in the attic, that is?
