I was there...and performed a little bit before all this went down. What happened was...some of the groups/artists ended up paying outrageous amounts of money to get up on the show...seeing how everyone thought they'd be opening for Webbie.
One group paid a stack to get the time slot right before Webbie was supposed to hit the stage. The only problem was....Webbie was nowhere in sight. Some how...SOME way...the promoters who were "supposedly" from Webbie's camp were able to get one over on everybody involved in actually makin' the show happen.
Those promoters had no direct involvement with any of Webbie's people. They took all the artists' money...and booked. That's what initiated everything that took place. Shit just escalated into something entirely different...
