Disco, so did the mics keep functioning throughout the show to the end, how did the recording come out? That ought to give some indication on how much the rain wetness affected the mics and their sound. What kind of mics were they? I hope they were not real expensive jobs! I guess some mics could survive getting drenched, while others might not fair so well. I hope you are able to give them a good thorough drying out and they continue to work up to spec. I personally would never let my expensive mics get wet and I always make sure to know the weather forecasts when I go to an outdoor arena or venue. But then again, sadly, these days I hardly get out anywhere anymore to record. Hope all goes well with your mics!
