As far as the economy not being able take a lockdown is concerned, I agree, but if there is an easing of our confinement, large public gatherings will be the last prohibition lifted.
Last night the Chief Medical Officer was talking in terms of at least 6 months, before we see the return of something approaching normality.
Personally, I very much doubt if any large festival, or even small festival will happen before September, possibly none before the end of this year.
