Yes, I too have played at many a "no-power" event. Caterer used Sternos for things that needed to be warm, and coolers full of ice as Gary mentioned. I did one (a 3 piece combo) recently where there was power maybe 600-700' away, but no one wanted to attempt to run that long of power cords! :-) They had a BBQ smoker, lots of cold drinks, and my band (trio) playing music for ~3 hours (with breaks of course), all on batteries. A couple of months ago, a duo (me plus guitarist who sings too) for a neighborhood event, it was sort of in a wooded are behind all of the houses, near a lake. Power was maybe 400-500' away. The event went on w/o any AC power . . . -Jim
