This film was screened on the BBC Television in 2008 and a book has also been published describing the passion of Ralph Vaughan Williams with women that he was connected with during his life and the influence it had on his creative compositions and the ideas that were translated into musical thoughts. This is a brilliant documentary done by John Bridcut, giving details about Vaughan Williams' marriage to his disabled wife Adeline and his affair with the woman who became his second wife, Ursula. Bridcut neatly explains the effect these relationships had on the music and demonstrates this by playing some performances of his choral and orchestral works. The film was sot at Cadogan Hall in London and the music is covered by the Philharmonia Orchestra of London, directed by Richard Hickox. The singers are of the Schola Cantorum of Oxford.
Among the contributors to this film is the (late) Ursula Vaughan Williams, who was interviewed shortly before she died at the age of 96 in 2008.
Once you are through with the film, listen to his Pastoral Symphony.
