Gary Ronald McFarland (October 23, 1933 – November 2, 1971[1]) was an American composer, arranger, conductor, vibraphonist, and vocalist.

He attained a small following after working with jazz luminaries Bill Evans, Gerry Mulligan, Johnny Hodges, John Lewis, Stan Getz, Bob Brookmeyer, and Anita O'Day.

[1] As well as his own albums and arrangements for other musicians he composed the scores to the films Eye of the Devil (1966) and Who Killed Mary What's 'Er Name?

However, at age 38, on November 2, 1971—the same day that he completed the Broadway album, To Live Another Summer; To Pass Another Winter—McFarland died in New York City at St. Vincent's Hospital from a lethal dose of liquid methadone that he had ingested at Bar 55 at 55 Christopher Street in Greenwich Village.

[1][6] McFarland had been married since 1963 to Gail Evelyn Frankel (maiden; 1942–2007); they had a son, Milo (1964–2002), and a daughter, Kerry.
