"Jamboree author Black is a graduate of five penitentiaries, was pried loose from a 25-year prison term and helped to overcome his addiction to narcotics by mustachioed Editor Fremont Older of the San Francisco Call-Bulletin. This play is a dramatization of Black's book You Can't Win. "Every character in this play is drawn from the personal experiences of Jack Black during his years as a criminal or as a prisoner. The types are real and these people actually lived."
