Back in the 90's, it was always touch-and-go as to whether Glasto would sell out. If it rained one year, it wouldn't sell out the next, and you could simply just turn up and buy a ticket on the gate.
But in the early 2000's, demand just sky-rocketed (as they say) largely due to the widespread use of the world-wide internet, and increased TV coverage of the event. The whole Glasto experience became demystified.
It was always a great weekend but only those 'in the know' would realise this.
Unbelievably, the demand has exceeded half a million in the last few years (with capacity at 100-150,000) despite a succession of festivals with appalling weather-by definition the 400,000 who were turned down for tickets each year didn't get to see how hideous a wet, muddy Glasto really was.
The mud and rain never seem that bad on telly.
Michael Eavis has scored a huge own-goal by making a rapper the headline artist. The people who really love rap music generally aren't the kind of people who love spending a weekend on a muddy festival site (with some exceptions, obviously!).
Following last year's increasingly middle-aged crowd, Eavis wanted specifically to attract a younger crowd this time and, in his simplistic, (and frankly patronising) mind, all young people simply adore rap music!
Absolute colloaks (as my phone would mis-predict).
Musical taste relates much more to personality type than to age - witness the broad age-range we have here on this very website.
It will probably still sell out but demand is down massively this year, and rightly so. Hopefully, Eavis will have learnt his lesson.
