Just checked link - its working.
But no mention of him being sick, or having issues.
Actually what they are saying, bizarre as it is, is that the strobe lights that they were using on stage were too intense and caused him to have a seizure on stage and he died from the seizure. Supposedly, he actually asked the crew to turn off the lights because he was having problems and for whatever reason they didnt turn them off and he had the seizure.
Ministry shows are pretty intense so the strobes dont surprise me.
