I was trying to confirm what could (theoretically) happen when according the government's roadmap dates yesterday.

It looked like as of 17th May large outdoor events could take place. And indoor events with attendees in clusters of 6 or two households (ie social distancing)

And then from June 21st, all restrictions lifted. So theoretically at least, all festivals post 21 June would at least be legal however they were organised.

I was looking at the London Folk Festival, which is scheduled to take place in a couple of indoor venues including Cecil Sharp House, between 18th and 20th June. Kind of annoying scheduling as if it were the following weekend it would not require any indoor social distancing measures at all.

'Course all of that is theoretical, in practice they all depend on the success of the previous stage so there could be a domino effect on the dates.
