But now, I think I know. They must have been "in the zone", focusing on their music and trying to entertain. I got a taste of this the other day when, while the Eyewitness Blues Band played holiday songs outside Macy's Union Square, my car got towed. I was standing no more than 25 feet away at the time, and I had no idea my car was gone until I went to stow my gear in it after we wrapped.

What I do know is that I never thought I'd see the day when my car could be towed from practically beneath my nose without noticing. Apparently, life changes when you have a guitar in your hand.
