From the wiki: “‘Terry’s Theme’ was composed by Charles Chaplin (née Charlie Chaplin), with lyrics by the English lyricists Geoff Parsons and John Turner. The music was first used for Chaplin’s film Limelight (1952) titled ‘Terry’s Theme’. The music for the film was belatedly awarded an Oscar for Best Original Dramatic Score at the 45th Academy Awards in 1973.
“Chaplin spent more than two years writing Limelight. His method was remarkable, and unique in his work. As a preliminary, he wrote the story in the form of a full-length novel – some 100,000 words long and entitled ‘Footlights’. The novel – never published in Chaplin’s lifetime or apparently even intended for publication – relates the story as it appears in the finished film.
