Barry Gray (born John Livesey Eccles;[2] 18 July 1908 – 26 April 1984) was a British musician and composer best known for his collaborations with television and film producer Gerry Anderson.

After serving for six years with the Royal Air Force during World War II[4] he returned to the music industry to work with such names as Vera Lynn and Hoagy Carmichael.

Gray's professional association with Anderson and his career in TV and film scoring ended when he decided to leave the production of Space: 1999 after the completion of the first series.

[10] The scenes of Ross and Kane's journey to the Counter-Earth are accompanied by a piece titled "Sleeping Astronauts" featuring the Ondes Martenot, played by French ondiste Sylvette Allart.

[1][10] Archer and Hearn describe this piece as "one of the most enchanting" ever written by Gray, adding that the soundtrack as a whole evokes a "traditional Hollywood feel" in contrast with the film's future setting.

On the evening of 8 November 2008, to mark the centenary year of Gray's birth, a concert was held in the Royal Festival Hall at London's South Bank Centre.

[11] Ralph Titterton, restorer of the Gray archive and co-producer of the original soundtrack CDs, and Cathy Ford, a librarian, researcher and biographer, joined film composer, conductor and arranger François Evans to produce the event in aid of the Cinema and Television Benevolent Fund.
