Task: Question Answering
Input (English): Passage: At Eynsford, with Moeran as his co-tenant, Heseltine presided over a bohemian household with a flexible population of artists, musicians and friends. Moeran had studied at the Royal College of Music before and after the First World War; he avidly collected folk music and had admired Delius during his youth. Although they had much in common, he and Heseltine rarely worked together, though they did co-write a song, "Maltworms". The other permanent Eynsford residents were Barbara Peache, Heseltine's long-term girlfriend whom he had known since the early 1920s, and Hal Collins, a New Zealand Māori who acted as a general factotum. Peache was described by Delius's assistant Eric Fenby as "a very quiet, attractive girl, quite different from Phil's usual types". Although not formally trained, Collins was a gifted graphic designer and occasional composer, who sometimes assisted Heseltine. The household was augmented at various times by the composers William Walton and Constant Lambert, the artist Nina Hamnett, and sundry acquaintances of both sexes.The ambience at Eynsford was one of alcohol (the "Five Bells" public house was conveniently across the road) and uninhibited sexual activity. These years are the primary basis for the Warlock legends of wild living and debauchery. Visitors to the house left accounts of orgies, all-night drunken parties, and rough horseplay that at least once brought police intervention. However, such activities were mainly confined to weekends; within this unconventional setting Heseltine accomplished much work, including settings from the Jacobean dramatist John Webster and the modern poet Hilaire Belloc, and the Capriol Suite in versions for string and full orchestra. Heseltine continued to transcribe early music, wrote articles and criticism, and finished the book on Gesualdo. He attempted to restore the reputation of a neglected Elizabethan composer, Thomas Whythorne, with a long pamphlet which, years later, brought significant amendments to Whythorne's entry in The History of Music in England. He also wrote a general study of Elizabethan music, The English Ayre.In January 1927, Heseltine's string serenade was recorded for the National Gramophonic Society, by John Barbirolli and an improvised chamber orchestra. A year later, HMV recorded the ballad "Captain Stratton's Fancy", sung by Peter Dawson. These two are the only recordings of Heseltine's music released during his lifetime. His association with the poet and journalist Bruce Blunt led to the popular Christmas anthem "Bethlehem Down", which the pair wrote in 1927 to raise money for their Christmas drinking. By the summer of 1928 his general lifestyle had created severe financial problems, despite his industry. In October he was forced to give up the cottage at Eynsford, and returned to Cefn Bryntalch. 
Question: What is the name of the person with whom Heseltine co-wrote the song, "Maltworms"?
Output (English): Moeran.
