Question: What opera was composed by an english composer who was born on the 12th of October 1872 and died on the 26th of August 1958?

full_context: Document 1: Lovely Joan: Lovely Joan is a traditional English folk song (Roud #592), and the tune to which it is sung. Its melody is most familiar to modern audiences as the counterpoint tune used in British composer Ralph Greaves's arrangement of "Fantasia on "Greensleeves"" from Ralph Vaughan Williams's opera "Sir John in Love"."
Document 2: Four Last Songs (Vaughan Williams): Ralph Vaughan Williams' Four Last Songs cycle is made up of four songs: "Procris," "Tired," "Hands, Eyes, and Heart," and "Menelaus." All of the songs were composed between 1954 and 1958. The cycle is best suited for mezzo-soprano, although, the original program note from the cycle's 1959 premiere acknowledges that all of the songs may be sung by a baritone, except for "Hands, Eyes, and Heart" "which is a woman's song." It is suggested that the four songs were originally intended to be two separate song cycles with "Menelaus" and "Procris" belonging to one cycle and "Tired" and "Hands, Eyes, and Heart" belonging to another. However, there is debate in the scholarly community about this proposed song cycle grouping. Renée Chérie Clark in her essay, "A Critical Appraisal of Four Last Songs" suggests, citing a letter from the composer to a friend at Cornell University, that Vaughan Williams actually intended for "Menelaus" and "Hands, Eyes, and Heart" to be grouped together. The composer's death in 1958 left both cycles unfinished, and in 1960, they were assembled by the composer's widow, Ursula Vaughan Williams, and published as set by Oxford University Press. The texts of all four songs are poems written by Vaughan Williams' wife Ursula who penned several books of poetry throughout her lifetime as well as a biography of her late husband. "Procris" and "Menelaus" deal with figures from ancient Greek and Roman mythology and epic poetry while "Tired" and "Hands, Eyes, and Heart" depict images of love between a husband and wife.
Document 3: The Lass of Richmond Hill: "The Lass of Richmond Hill", also known as "The Sweet Lass of Richmond Hill", is a song written by Leonard McNally with music composed by James Hook, and was first publicly performed in 1789. It was said to be a favourite of George III and, at one time, was thought to have been written by his son, George IV. It is a love ballad which popularized the poetic phrase "a rose without a thorn" as a romantic metaphor. Associated with the English town of Richmond in North Yorkshire, it is now often mistakenly considered to be a traditional or folk song, and has even been assigned the number 1246 on the Roud Folk Song Index. The music is also used as a military march by the British army.
Document 4: The Unquiet Grave: "The Unquiet Grave" is an English folk song in which a young man mourns his dead love too hard and prevents her from obtaining peace. It is thought to date from 1400 and was collected in 1868 by Francis James Child, as Child Ballad number 78. One of the more common tunes used for the ballad is the same as that used for the English ballad "Dives and Lazarus" and the Irish pub favorite "Star of the County Down".

Document 6: Jack Monroe (song): "Jack Monroe" (Roud 268 and Laws N7), also known as "Jack Munro," "Jackie Monroe," "Jacky Robinson", "Jack-A-Roe," "Jackaroe," "Jackaro," "Jackie Frazier," "Jack the Sailor," "Jack Went A-Sailing," "The Love of Polly and Jack Monroe", "The Maid of Chatham", among other titles, is a traditional ballad of uncertain (though presumably British) origin. American broadsides of the song date back to around 1830. The song is a staple of the folk rock repertoire and has been performed by Joan Baez, Bob Dylan, and more commonly, The Grateful Dead (as "Jack-A-Roe"). In 1931, Florence Reece used this tune for her song "Which Side Are You On?". Also performed by Melora Creager of Rasputina on Ancient Cross-Dressing Songs.

Tommy, one of the tourists, falls in love with Fiona, a young woman from Brigadoon.

He composed it from 1956 to 1957 and it was given its premiere performance in London by the Royal Philharmonic Orchestra conducted by Malcolm Sargent on 2 April 1958, in the composer's eighty-sixth year. It was subsequently performed on 5 August 1958 by the BBC Symphony Orchestra under the direction of Malcolm Sargent at a Promenade Concert. Vaughan Williams died three weeks later, on 26 August, the very day on which the symphony was due to be recorded for the first time, by the London Philharmonic Orchestra conducted by Sir Adrian Boult. The composer had planned to attend the recording sessions.

Document 10: Joan (album): Joan is a 1967 album by Joan Baez. Having exhausted the standard voice/guitar folksong format by 1967, Baez collaborated with composer Peter Schickele (with whom she'd worked on the 1966 Christmas album, "Noël"), on an album of orchestrated covers of mostly then-current pop and rock and roll songs. Works by Donovan, Paul Simon, Tim Hardin, the Beatles, and Richard Fariña were included, as well as selections by Jacques Brel and Edgar Allan Poe.
Document 11: Green Bushes: Green Bushes is an English folk song (Roud #1040, Laws P2) which is featured in the second movement of Ralph Vaughan Williams' "English Folk Song Suite", in Percy Grainger's "Green Bushes (Passacaglia on an English Folksong)", and in George Butterworth's "The Banks of Green Willow". The melody is very similar to that of the "Lost Lady Found" movement of Percy Grainger's Lincolnshire Posy, and to The Cutty Wren.
Document 12: A Sea Symphony: A Sea Symphony is a piece for orchestra and chorus by Ralph Vaughan Williams, written between 1903 and 1909. Vaughan Williams' first and longest symphony, it was first performed at the Leeds Festival in 1910, with the composer conducting. The symphony's maturity belies the composer's relative youth when it was written (he was 30 when he first began sketching it). One of the first symphonies in which a choir is used throughout the work and is an integral part of the musical texture, "A Sea Symphony" helped set the stage for a new era of symphonic and choral music in Britain during the first half of the 20th century. The work is sometimes referred to as the Symphony No. 1.
