 By 1975, the stranglehold of Joint promotions had almost crumbled, with many of its founding members retiring and the company being bought out several times, leading to the wrestling industry being run by a public company with little experience of the unique business.Finally, promotions were left in the hands of Max Crabtree, the brother of Shirley, who was headhunted by Joint as the most experienced booker still in the business.Crabtree produced the next boom in British wrestling by creating the legend of "Big Daddy", the alter ego of Shirley, who had been unemployed for the best part of 15 years.
