It is possible that a Jimmy's character is loosely based on Tom Silverman, founder of Tommy Boy Records. His appearance is accurate, but the label is placed in New York City.
Silverman has dark brown hair and wears a red cap, a letterman jacket over a black shirt and khaki shorts.
Events of GTA San Andreas
After Madd Dogg and Carl Johnson chase OG Loc and retrieve Madd Dogg's rhyme book at the Blastin' Fools Records building in Los Santos, Silverman threatens to sue OG Loc and presumably drops him from the Blastin' Fools Records label.
