PROBLEM: Passage: Lennon was born on 9 October 1940 at Liverpool Maternity Hospital, to Julia (née Stanley) (1914–1958) and Alfred Lennon (1912–1976). Alfred was a merchant seaman of Irish descent who was away at the time of his son's birth. His parents named him John Winston Lennon after his paternal grandfather, John "Jack" Lennon, and Prime Minister Winston Churchill. His father was often away from home but sent regular pay cheques to 9 Newcastle Road, Liverpool, where Lennon lived with his mother; the cheques stopped when he went absent without leave in February 1944. When he eventually came home six months later, he offered to look after the family, but Julia, by then pregnant with another man's child, rejected the idea. After her sister Mimi complained to Liverpool's Social Services twice, Julia gave her custody of Lennon. In July 1946, Lennon's father visited her and took his son to Blackpool, secretly intending to emigrate to New Zealand with him. Julia followed them – with her partner at the time, Bobby Dykins – and after a heated argument, his father forced the five-year-old to choose between them. In one account of this incident, Lennon twice chose his father, but as his mother walked away, he began to cry and followed her. According to author Mark Lewisohn, however, Lennon's parents agreed that Julia should take him and give him a home. A witness who was there that day, Billy Hall, has said that the dramatic portrayal of a young John Lennon being forced to make a decision between his parents is inaccurate. Lennon had no further contact with Alf for close to 20 years.Throughout the rest of his childhood and adolescence, Lennon lived at Mendips, 251 Menlove Avenue, Woolton, with Mimi and her husband George Toogood Smith, who had no children of their own. His aunt purchased volumes of short stories for him, and his uncle, a dairyman at his family's farm, bought him a mouth organ and engaged him in solving crossword puzzles. Julia visited Mendips on a regular basis, and when John was 11 years old, he often visited her at 1 Blomfield Road, Liverpool, where she played him Elvis Presley records, taught him the banjo, and showed him how to play "Ain't That a Shame" by Fats Domino. In September 1980, Lennon commented about his family and his rebellious nature:. 
Question: What was the name of the person that witnessed the heated scene between Julia and Alfred Lennon?

SOLUTION: Billy Hall.

PROBLEM: Passage: The Sitwells looked after their protégé both materially and culturally, giving him not only a home but a stimulating cultural education. He took music lessons with Ernest Ansermet, Ferruccio Busoni and Edward J. Dent. He attended the Russian ballet, met Stravinsky and Gershwin, heard the Savoy Orpheans at the Savoy Hotel and wrote an experimental string quartet heavily influenced by the Second Viennese School that was performed at a festival of new music at Salzburg in 1923. Alban Berg heard the performance and was impressed enough to take Walton to meet Arnold Schoenberg, Berg's teacher and the founder of the Second Viennese School.In 1923, in collaboration with Edith Sitwell, Walton had his first great success, though at first it was a succès de scandale. Façade was first performed in public at the Aeolian Hall, London, on 12 June. The work consisted of Edith's verses, which she recited through a megaphone from behind a screen, while Walton conducted an ensemble of six players in his accompanying music. The press was generally condemnatory. Walton's biographer Michael Kennedy cites as typical a contemporary headline: "Drivel That They Paid to Hear". The Daily Express loathed the work, but admitted that it was naggingly memorable. The Manchester Guardian wrote of "relentless cacophony". The Observer condemned the verses and dismissed Walton's music as "harmless". In The Illustrated London News, Dent was much more appreciative: "The audience was at first inclined to treat the whole thing as an absurd joke, but there is always a surprisingly serious element in Miss Sitwell's poetry and Mr Walton's music ... which soon induced the audience to listen with breathless attention." In The Sunday Times, Ernest Newman said of Walton, "as a musical joker he is a jewel of the first water".Among the audience were Evelyn Waugh, Virginia Woolf and Noël Coward. The last was so outraged by the avant-garde nature of Sitwell's verses and the staging, that he marched out ostentatiously during the performance. The players did not like the music: the clarinettist, Charles Draper asked the composer, "Mr Walton, has a clarinet player ever done you an injury?" Nevertheless, the work soon became accepted, and within a decade Walton's music was used for the popular Façade ballet, choreographed by Frederick Ashton. 
Question: What is the name of the Sitwell's protégé who they looked after both materially and culturally?

SOLUTION:
Walton.
