I have never had to play a gig where I was really sick, just some coughs and aches. However, my last gig a little over a week ago had its own problems.
I had to drive through a major snow storm. I had to work up in Green Bay, I teach computer classes. It was a night class, I ended the class early on last Friday night at 9:30. I had to be back for a gig in Milwaukee at Midnight. Well, after I end class, I have to go back the motel, get my stuff and check out. The drive is roughly 100 miles. In good weather this isnt a problem, but on that night some areas got close to a foot of snow.
I made it to the show by 12:30. I saw at least 8 cars off the road on my way back to Milwaukee, but I made it.
As I walk in, my band was in the middle of trying to show one of the opening bands players the basic structure of our songs. They didnt think I was going to make it through the storm to the show. I almost didnt, I was very very close to pulling over, it was terrible out there.
