Hidden away in a brief news item at the start of this month is an interview with Michael Eavis where he says that realistically, there's a good chance he'll have to cancel the festival again for 2021 due to Covid.
250,000 people crammed into a fairly small space with no spcial distancing is prime breeding conditions for Covid, and you'd have tens of thousands of people potentially spreading the virus across the UK. Then there's travel restrictions between countries. If the same restrictions today are still in place next year, it's impossible for most international acts to come to perform.
Of course things might change and hopefully they do but prepare yourselves for another barren summer of festivals in 2021. We should find out in a month or two whether the normal sale of tickets is going ahead and if so then Eavis will be confident he can run a festival next year. If not then we'll have to wait and see...
