In an interview for a 2010 BBC Radio 4 documentary on his life and career, Preston's manager Joyce Moore revealed that after she began handling his affairs, Preston opened up to her about the lifelong trauma he had suffered as the result of being sexually abused as a child. Preston told Moore that at about the age of nine, after he and his mother moved to Los Angeles from Houston to perform in a touring production of "Amos 'n' Andy", he was repeatedly abused by the touring company's pianist. When Preston told his mother about the abuse, she did not believe him, and failed to protect him. The abuse went on for the entire summer, and Preston was also later abused by a local pastor.
