This is an easy one. Stone Henge 1980-something. All my mates were going but I was working every hour and saving every penny for a trip to India and Ladakh. So I said I’d go next year. Of course that year was so good it was banned from ever happening again.
Answering a related but unasked question: The Au Pairs. They were supposed to be playing at an RAR thing in Vicky Park so I convinced a few mates to make the trip up there. We saw The Slits, The Raincoats, The Pop Group, John Cooper Clark, several others before we worked out that The Au Pairs had cried off. But they were booked to support Toyah at the Lyceum that night so off we went to the Strand by public transport and arrived just after they finished their set. A few weeks later they were supporting at Hammersmith Odeon. And once again they were a no-show, replaced by Steel Pulse. But I remember being so blown away by Steel Pulse I have absolutely no recollection who was headlining that gig.
