According to our sources, a deal really was in place for CB to perform at the September 7 event, but details of the performance never got to Chris.

We're told the talent agency that booked the gig for Chris believed the event promoters had breached the contract -- by using the wrong pic of Chris on posters -- so they never told him about the deal, which is why he never showed
