The former chairman of Motown Records sues Sixto Rodriguez for representations made 45 years ago. Searching for Sugar Man star Sixto Rodriguez spent years out of the limelight until an Oscar-winning documentary showcased how the Michigan-born songwriter had secretly become a huge star in South Africa. Stardom has its price, though. Now, the newly famous musician is facing trouble over representations he made to music executives in the 1960s.The genesis of the legal dispute was first detailed by The Hollywood Reporter earlier this month. At the time, Rodriguez was not a party to the proceedings, but that is no longer the case. He’s now facing claims of breaching his songwriter deal.
