The Philharmonia Chorus was founded in 1957 by Walter Legge and took the same name as the Orchestra with which it was formed to sing: The Philharmonia Orchestra.
In 1964, Legge disbanded the orchestra who reformed itself as a body governed by its players, called the New Philharmonia Orchestra; The Chorus followed suit: New Philharmonia Chorus.
In 1977, the orchestra decided to resume its original name and the chorus also went back to first principles.
