Update - a pub where we were booked to play on 4th July believe that they will be allowed to open (with social distancing, natch) that weekend. They want to do an early-evening outdoor event in their large garden with a BBQ, and with us performing unplugged outside. As a band, we'd never actually need to enter the pub if we didn't want to.
Two of us have said we're up for that, the third wants 48 hours to think it through. I'll keep you posted.
