Well, I'm by no means pro level but I gig a lot. It can go perfectly at home, it can go perfectly at rehearsal but those are controlled environments. You can can do everything possible to pull a perfect gig but unfortunately, nothing can really prepare you for the many and varied distractions in a live situation - some of which will only catch the corner of your eye and distract you subconsciously. I long ago gave up listing the different things that could throw me sideways. Laugh it off, move on, even better, if you can turn it into a proper gag, like this example from one of my recent shows...
I'm trying to get more fluid and adventurous with my walking basslines, so I've just been letting it go, not being too worried about mistakes and trusting that good old fashioned trail/error/repeat works out. This particular night we're into the rock 'n' roll medley (12 bar in A, can't go wrong), the lead guitarist takes off and let my fingers wander. It starts well, I'm staying in key and then, suddenly, it's like my fingers have taken over; I'm playing the notes before my brain tells me to and I'm thinking, "Woah, hang on a minute, I'm actually doing it! It's natural, it's smooth, it amazing". I'm right there, in that zone.
Until the lead singer/rhythm guitarist leans into the mic and says, "Any chance you could play some root notes in there, mate, I can't keep up"?
I yell back, "I'm stuck in a jazz groove! Hit me on the back of the head"!
He swings his headstock at my bonce and gives me a smart whack. I keep going.
He says, "It didn't work"!
I reply, "Yeah, but now you're out of tune, so no one's staring at me anymore".
