Epstein added the Vic Lewis Organisation to NEMS in 1966, and later brought impresario Robert Stigwood in as a manager. He once offered to sell the control of NEMS to Stigwood, without telling any of his artists about the offer. McCartney was taking a more active interest in NEMS' finances, as it became known that some artists with more ruthless managers claimed to be benefiting from more commercially advantageous terms, such as the Rolling Stones under the management of Allen Klein. After Epstein's death, Clive Epstein assumed control of NEMS as the company's second-largest shareholder. Stigwood then tried to take over management of NEMS but all four Beatles vigorously objected, with Lennon saying, "We don't know you. Why would we do this?"
