John Cacavas (August 13, 1930 – January 28, 2014) was an American composer and conductor probably best known for his television scores, such as Kojak, for which he was the chief composer. He composed the show's third main title theme for its 5th and final season in 1977-1978.
John Harry Cacavas was born in Aberdeen, South Dakota in 1930. His father was an immigrant from Greece and his mother was born in North Dakota. He had a fraternal twin sister, Jeanne, and they had numerous siblings: Peter David, b. 1928; Penelope, b. 1932; and Adrian G., 1933. Their father's younger brother Chris had also immigrated to South Dakota and lived in Aberdeen, where he married and had a family. John and his siblings attended local schools; he displayed an early talent for music, forming a local band at age 14. He studied musical composition at Northwestern University.
During service in the military, Cacavas was assigned to Washington, DC where he was an arranger for the United States Army Band. There he met Charles Osgood, with whom he collaborated on musical compositions and recordings. Osgood later became a radio and TV commentator.
After studying music, in the 1960s Cacavas and Osgood collaborated, including on US Senator Everett Dirksen's recording of Gallant Men, which won a Grammy Award for a spoken word performance. While working in London in the 1970s, Cacavas met actor Telly Savalas, who later helped him move into working on movie scores. Cacavas scored Savalas's 1972 cult horror film Horror Express, and he moved to Hollywood, where he began to compose scores for television series and movies produced for TV. His most noted scores were written for the series Kojak (1973-1978), for which he was the chief composer. For its 5th and final season in 1977-1978, Cacavas composed the show's third main title theme.
His television credits are extensive, including scoring the series Hawaii Five-O, The Bionic Woman, Mrs. Columbo, The Eddie Capra Mysteries, and Buck Rogers in the 25th Century, as well as television movies, such as The Elevator (1974), Friendly Persuasion (1975), Murder at the World Series (1977), SST: Death Flight (1977), Superdome (1978), The Time Machine (1978) and the 1982 film The Executioner's Song, starring Tommy Lee Jones. Scoring music for the 1981 television movie Hellinger's Law reunited him with Kojak veteran and friend Telly Savalas, and Cacavas also went on to score Savalas's made for TV Dirty Dozen sequel movies The Dirty Dozen: The Deadly Mission (1987) and The Dirty Dozen: The Fatal Mission (1988). His later television work included popular miniseries such as Jenny's War (1985) and Perfect Murder, Perfect Town in 2000.
