スーパースター・ビリー・グラハム
Known as somewhat of a legitimate "tough guy" shootfighter outside of the ring, Perez was reputedly one of the few men who escaped the notorious submission "sugar hold" of Stu Hart in his famed basement training facility, "The Dungeon" during a short stay in the Calgary, Alberta, Canada promotion. This was confirmed by former pro wrestling star Superstar Billy Graham who was training at the gym during the late 1960s.
