Former boxing champion Mike Tyson will be master of ceremony at the launch of his rapper friend MARK 'THE MACK' MORRISON's comeback album tomorrow night (24MAR06). Tyson will help promote British Morrison's new disc INNOCENT MAN at the event in Brighton, England. Morrison's publicist says, "They're old friends. Mark heard that Mike was in the UK, and seeing as they were going to hook up anyway he asked him to help out with the party. "I'm not sure exactly how they know each other but apparently they go way back." Morrison was jailed in 1998 for sending a lookalike to perform community service in his place, while Tyson was sentenced to six years for the alleged rape of Miss Black Rhode Island, Desiree Washington, in 1992.
