Played a packed show in the middle of August in a room with broken air conditioning. We always used to wear polyester suits and a couple of my mates had a real big thing about us not stripping off layers during the set.
Well, a couple of beers before the gig and not enough water during and I almost collapsed halfway through our set of heat exhaustion.
You know that feeling when you're dehydrated and you actually get the chills? Yeah, scary stuff...
Luckily, a friend brought a bottle of water up onstage and I chugged the whole thing just in the nick of time between songs. I didn't collapse and was able to finish the set...here's a shot of me during the set.
Yeah, it kinda looks like I fell in a swimming pool...you can see a single dry spot on the collar of my shirt.
