I think my overly glib reply needs expanding upon. I prefer to get it right. Every time. I do not have a phone it in, "that'll do" approach and never had. Serious bloops need addressed as a band.
I think my mistake management has improved. When I started out, I would be very uptight and small mistakes would put me off a lot - my drummer is still mentally scarred by the "death stare of '09" when he had the audacity to miss a snare I was expecting! Nowadays, I am a lot better at recovery when I make a mistake, and see other people's mistakes as an opportunity for humour - a knowing look with a smile tends to get a better performance out of others than a death stare. Looks better from an audience point of view - whether they notice the mistake or not, they see a band having a good time, so they feel predisposed to having a good time. Good vibes transmit way better than a scowl or grimace of "F F F BolloX I made a mistake!" followed by several bars of self flagellation. Forget about it for now, pick up the song ASAP. The time for discussion/review is after the gig, not during.
