He also wrote and arranged music for "Friday Night is Music Night", as well as numerous other BBC programmes. A CD of his original compositions for orchestra performed by the BBC Concert Orchestra conducted by Rumon Gamba was released in 2003. Langford produced many choral arrangements for the King's Singers in the 1970s. He was also known for his theatre compositions, such as "The Crooked Mile" and "The House of Cards". Langford was often used by Hollywood as a score orchestrator, with "Return of the Jedi", "Superman II", "The First Great Train Robbery", "Clash of the Titans" and "Return to Oz" to his name. In 1974 he released a demo album entitled "The Amazing Music of the Electronic ARP Synthesizer". This contained several compositions of his own, plus cover versions, played entirely on the then new innovation, the ARP synth, of pieces as diverse as "Yellow Submarine", "Raindrops Keep Fallin' on My Head", "Cocktails for Two", "Light Cavalry Overture" and Mozart's Symphony No. 40. Later compositions include his "Berceuse and Burlesque" for bassoon and orchestra, performed on 1 February 2008 at Axminster.
