Ah the googling was today, the ticket was bought back in the mists of time, probably by sending a postal order with SAE to the venue direct.
Hard for the yoof of today to believe, but no Internet or google or ticketmaster back then to do all your work for you. One had to be crafty back then to get a ticket to the popular gigs. We would keep an eye on MM and NME and see whether some enterprising journalist had a sniff of a tour to come. Then we'd load up on 2p pieces (new money) and head to the nearest phone box with a list of venues in hand. Call directory enquiries (free in those days) and get the numbers, and call the place direct.
Always get straight through the the guy in the box office (none of these call centres in God knows where) and ask direct if xxxxx was going to be playing there soon. They'd either say they were still trying to get them (which means No) or they'd shuffle some papers and tell us the exact date the band on the yet to be announced tour was going to play there.
As always, we'd get the price of the gig and be told to send a postal order with SAE to the venue directly. No frigging booking or convenience charge, the price on the ticket was the price you paid, and they filled the SAE in the order they received them.
So without fail we would get to see our favourite band, usually in several locations, and the tickets would sell out immediately the tour was officially announced. But we knew about it months in advance.
