He was educated at Sutton High School in Plymouth and (showing an aptitude for music very early) studied piano, harmony and counterpoint privately.
[1] Knight worked with light entertainment stars including Petula Clark, Marty Wilde, Sammy Davis Jr.,[5] and Edmund Hockridge, and in shows ranging from Spot the Tune (1956) with Jackie Rae and Marion Ryan to the comedy series Home to Roost (1985).
In between, other highlights of his career were as: Following his death, Yorkshire Television launched the annual Peter Knight Award to honour excellence in musical arranging.
He was conductor for many songs for Scott Walker's 1960's period, and became famous for his rich lush orchestration for The Moody Blues' Days of Future Passed, most widely known through the single "Nights in White Satin".
On the special edition CD of the music from these two shows, Knight arranged three of the extended medleys and ten of the single charts.
Knight also wrote arrangements for the King's Singers, including the Airwave song "You are the New Day", now a best-selling title in the USA.
