I resigned from the Army back in 2001 when Peter was kicked out and the mess that followed it. I was however able to see the original line up when they came to St Louis in 2000 for the "Farewell Tour". Skid Row and Ted Nugent were the openers. Several interesting things happened during their sets, but since this is a KISS topic I'll stick to them.
By the time they took the stage it was well past dark, but the temp was in the high 90's with plenty of humidity. So as miserable as the crowd was in the heat, KISS must have been in pure hell in full costume. Gene was sweating like a pig before they even got to the first verse of Detroit Rock City and Paul lost his top as soon as it was over. The rest of the gig was the typical paint by numbers KISS show, till Rock n Roll All Nite. Ace came out for the first time ever in only half costume to finish up, he had put a t shirt on in place of his huge space vest. I believe the KISS website still has pictures of the gig. This was Aug 26th I believe if anyone wants to track them down.
Anyway, a few months later Pete left, Singer came back in, KISS Kasket... I turned in my membership and went into recovery.
