Bill Faversham, President of the Louisville Sponsoring Group. On the February 25, 1964 Title fight and Rematch Agreement. Cassius Clay would have never gotten the Title Fight with Sonny Liston, unless we agreed to a rematch clause. We agreed in principal, and also signed a seperate agreement. Furthermore, we have advised Cassius Clay, that failure to perform this legal and valid contract, would result in Cassius Clay and the LSG (Louisville Sponsoring Group) in a breach of contract, resulting in very substantial damages.
