Long before Donald Trump (aka Donald Drumpf) was running for president, or even featured on The Apprentice, the real estate mogul was involved in a business venture with legendary rockers The Rolling Stones. An old story from 1989 has recently resurfaced, thanks to a Salon article, and we can’t get enough.As the story goes, the last night of the Stones’ tour was set for Boardwalk Hall in Atlantic City, where the nearby Trump Plaza Hotel & Casino was sponsoring both the performance and a pay-per-view special. The band shrewdly made Trump agree to not promote the event outside of Atlantic City, and to not appear at the concert itself. Quite the foresight.Of course, Trump completely defied the previously-agreed upon arrangements. As tour promoter Michael Cohl told Pollstar last August. “I run to the press room in the next building and what do you think is happening? There’s Donald Trump giving a press conference, in our room!” Cohl claims that Trump said that someone “begged him to go up,” clearly lying to cover his breach of contract.Cohl called him out for being a liar, hoping to nip this problem in the bud. However, Trump made his way back to the press room, again speaking up to promote the show. Cohl tells the story of Keith Richards’ reaction best. “Keith pulls out his knife and slams it on the table and says, ‘What the hell do I have you for? Do I have to go over there and fire him myself? One of us is leaving the building – either him, or us.’”Perhaps unfortunately, Cohl wound up handling the situation without Richards’ threat of violence. Cohl went back to Trump and threatened to cancel the whole pay-per-view broadcast, only to have Trump’s guards pull out brass knuckles. The guards, however, were no match for the entire staff security team, who outnumbered them forty-to-three. In the end, Trump backed down, and the Stones rocked the show.
