Mr. Jazz – Self-proclaimed nickname of Dr. Heathcliff “Cliff” Huxtable (Bill Cosby), a black New York City obstetrician on the sitcom THE COSBY SHOW/NBC/1984-91 who was just crazy about jazz music and musicians.
Cliff had another nickname. It was “Baby Cakes,” a moniker given to him by his wife, Clair (Phylicia Rashad) when they attended Hillman College in Georgia. Cliff called Clair “Lum Lum.”
Note: THE COSBY SHOW wrote several famous musical artists into the show’s scripts, such as singer/songwriter Stevie Wonder and the legendary jazz trumpeter/bandleader Dizzy Gillespie (1917-1993).
On Season 2, Episode 17: “Play It Again, Russell” we learn that Cliff’s love of music runs in the family. His father, Russell (Earle Hyman) used to be a jazz trombone player. When his old band gets together to jam, he’s a bit rusty but he jumps in and jams with his old jazz buddies.
