 The people playing Kizzy, George, and Tom Harvey were born within  three years of each other. Leslie Uggams (qv) and  Georg Stanford Brown (qv) who played Kizzy and Tom were both born  in 1943 and Ben Vereen (qv) who played George was born in 1946.  This means that "Tom" was actually three years older than his  "father" and "Kizzy" was three years older than her "son."
