Know the songs so well that it becomes automatic and you can do it from muscle memory. As you mention, the gig will always present itself with many distractions, so you want your fingers to keep going when your attention wanders.
Aim for perfection, but don't beat yourself up if you don't achieve it. Bum notes are going to happen. It's the train wrecks you need to avoid.
I often run band songs while watching TV - usually sports. That way I am only half paying attention. The bars I play often have TV's playing sports all over the bar - one of the main distractions - so it's a good simulation.
Don't do this while learning the songs though. That needs your undivided attention.
