Question: By what type of music was this English composer who collaborated with Ella Mary Leather on "Twelve Traditional Carols from Herefordshire" influenced strongly?

Context:
Fantasia on Christmas Carols
Fantasia on Christmas Carols is a 1912 work for baritone, chorus, and orchestra by the English composer Ralph Vaughan Williams.
 First performed at the 1912 Three Choirs Festival at Hereford Cathedral, the work is a single movement of roughly twelve minutes which consists of the English folk carols "The truth sent from above", "Come all you worthy gentlemen" and "On Christmas night all Christians sing" (i.e. the Sussex Carol), all folk songs collected in southern England by Vaughan Williams and his friend Cecil Sharp a few years earlier.
 These are interposed with brief orchestral quotations from other carols, such as "The First Nowell".
 The early work remains popular with choral societies, and is sometimes paired with his longer Christmas work "Hodie" of 1954.
 There is also a version of the "Fantasia" which replaces the orchestra with strings and organ.
 A purely orchestral version, in which the solo vocal and choral parts were 'cued in' on the orchestral instruments, was performed in Studio 8H, New York, on 19 December 1943 by the NBC Symphony conducted by Leopold Stokowski.
 The broadcast of this unpublished version, which was presumably arranged by the conductor, has been released on a 'Guild Historical' CD and is also uploaded on YouTube.

 Pearce was married three times: Ella Mary (fl.
 1933); Jean Mary Macartney (1909–1956); and Betty (died c. 1987).
 Pearce's catchphrase sign-off of his news reports, "God bless you, and you", was for viewers and his third wife.
 Pearce was a devout Anglican.
