RIP, Metal Edge and Kerrang! Magazine interviewed Jon Bon Jovi months later and Jon was still buzzing about this Chicago show. He called it the "turning point of the whole tour". Aside from seeing U2 post-9/11, I'm not sure if I've ever seen an act work harder on a concert stage than I saw Bon Jovi on that given night. The rumor was that someone backstage was giving Job crap about not having the need for multiple shows and said something along the lines of it would be the last time the band played a place that big. This was enough to send Jon off the edge and what happened later that night was the band's longest show to date of their career.
Digging through some old items, I found this newspaper clip from 1993. It's pretty spot on (except for believing Alec was the keyboard player), but alas, it's a snapshot of the band at their most hungry.
