Soon after, Grossman and Mogull signed a publishing deal that gave Witmark one of its most lucrative clients, Bob Dylan. Grossman bought out Dylan's previous contract with Leeds Music and signed the then-unknown singer-songwriter to Witmark for an advance of $5000. Two years later in 1963, Peter, Paul & Mary scored two consecutive Top 10 hits with Dylan songs, launching Dylan's career, and this was followed by many more hits by artists covering Dylan's songs, alongside the growing commercial success of Dylan himself. Grossman benefited enormously from both deals, because he took a 25% commission as Dylan's manager, and he structured Dylan's publishing deal so that he received 50% of Witmark's share of Dylan's publishing income—a tactic that was later emulated by other leading artist managers such as David Geffen.
