One good thing is that You had it (no meaning that it should happen) but get throogh it normaly, now You know the situation and will respond better next time, if it happens.
I don't think it will happen again soon. I have heard people having something like this, but about 1 time in a year at heavy weather gigs. So, it is just like - some deamons in Your seamen.
It wasn't easy, the stage and gear question was 1,5 hour later than is should end and we had to play without soundcheck. I was so could that night, i saw my breath all the time, but all ended up normal.
