During Presley's 1957 tour of Canada, the concert promoter Oscar Davis offered to represent them as their manager. Moore and Black, who had seen Presley become a millionaire while still earning $200 or $100 a week themselves, were willing to work with Davis but the backing vocalists, the Jordanaires, were not, because they did not trust him. They lived off mostly $100 a week. True, Presley, too, had been paid only $100 a week, like them, but that was back in 1956. Once Hollywood had been introduced, Presley's salary had witnessed a dramatic rise, while Moore and Black continued living off $100 a week.
