I first went in 1983 and saw The Smiths - was with my parents 83 & 84. But 86 I went with friends ... went most years it was on from then till 98 (into the dance music years).
I paid for tickets when they were £16 each - the did volunteering a few times, bunked over the wall and then worked behind the bar.
I'm a fat middle aged woman now and would go tomorrow if I could.
I have been to many other festivals over the years but nothing compares - most other festivals are a big stage a little stage and maybe a comedy tent or something all in a big arena with a separate camping area (Leeds, Reding, Bestivl, V fest etc) - Glastonbury is a town with theatres, cinemas, live shows, kids area, comedy tent, big stage, slightly smaller stage, dance tent, another stage, hippy field, food, stalls, street performance, buskers, circus, another music stage, classes, politics, etc etc etc
I'd love to go again - I'd take my teenager...
