 Prior to the release of The Byrds ' Greatest Hits , the band decided to dispense with the services of their co @-@ managers Jim Dickson and Eddie Tickner . The relationship between Dickson and the band had soured over recent months , and he and Tickner 's business arrangement with the Byrds was officially dissolved on June 30 , 1967 . At Crosby 's recommendation , Larry Spector was brought in to handle the Byrds ' business affairs , with the group electing to manage themselves to a large extent .
