Yep, it is no longer their fault if it goes bad, it is just down to the public.
I would say it is up to the person who is being asked if they want to or not. I would, but I wouldn't critisize anyone for not wanting to and instead waiting if that is what they wanted.
We have actually had no problem practicing but our guitarist doesn't want to play indoor venues but he is ok to practice.
He decided to leave the band as he didn't want to do indoor venues, fair enough, his choice, so we got some other guitarists to cover him, then it turned out those guitarists had forgotten they had a gig, then he decided he would come back as it was a big airy venue, then the singers son got covid and he has to isolate.
Then the gig the guitarists forgot they had got cancelled due to covid, so they are playing the gig with their band!
Going to be an odd time for gigging for a while.
As a result, still no gig. Next weekend there is supposed to be one, outdoors. I have not got excited about the idea as after 3 cancelled gigs in a row, I can't persuade myself that it is going to happen!
