There's me thinking I was the only one to mess up regularly - pleased to hear I'm not alone π€
My clangers are a standing joke amongst my band mates, and it's not often I can get through a gig without hitting a bummer or three π
OP asks how do we cope?
In my case, without a care in the world π Playing covers for almost 50 years, I've been getting away with mediocre for long enough to get used to it π€£
