You could insist on seeing proof of being double jabbed or of a recent negative test result but I think that would, along with those nervous of attending, deplete the numbers even further. I am double jabbed but still avoid, whenever possible, close contact and groups of any sort and until there is a marked and sustainable reduction in infections I'll be continuing this behaviour. The link between infections and hospitalisations is definitely being eroded but there is a way to go yet. Not that any of this matters personally because, as of yesterday, I now no longer own any bass gear whatsoever so my attendance is a moot point!
