Sam Hui Special 1980 presents a string of Sam Hui's songs in story form, joined by guest performers including Teresa Carpio, Ricky Hui, Wong Ching, Kwok Lee-man, Eunice Lam, James Wong and Winnie Yu. In the story, Sam's boss demands that he write more than a dozen new songs. Drawing on everyday life and the state of society, Sam comes up with numbers such as 搵嘢做, which urges people to work hard to get ahead; 先敬羅衣後敬人, on the importance of dressing sharp; and 每事問, which teaches students to question everything in order to learn — plus 夜夜念奴嬌, 尖沙咀Susie, 這一曲送給您, 傀儡 and more.
