Question: Passage: Lennon was born on 9 October 1940 at Liverpool Maternity Hospital, to Julia (nee Stanley) (19141958) and Alfred Lennon (19121976). 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?

Answer: Billy Hall.

Question: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999).
Question: What is the full name of the person who was the regular conductor of Ensemble Modern?

Answer: Peter Rundel.

Question: Passage: In the 1830s an aboriginal is charged with the spearing of a white settler, but was about to be released by the Captain convinced of his innocence after questioning him. But, during a party that night, a drunken officer shoots and kills the prisoner, and is charged with his murder.
Thomas Morland, the acting Attorney General, is sent to Newcastle to investigate.
Captain Alcot wishes to keep on the good side of the land-hungry Carlton so they attempt to defend the drunken lieutenant who has shot a native. Neither believe the prisoner Jacko had anything to do with the murder of a white settler, since he was captured 60 miles away from the crime. So they bribe Sergeant Constantine, who arrested Jacko, into saying that the place of arrest was close to Newcastle.
At a trial in Sydney, the lieutenant is charged with murder by the Acting Attorney-General. False testimony by Constantine brings a verdict of not guilty; but the playwright makes it clear that it is as much a victory as a defeat"people will have second thoughts" about molesting aborigines after this.
Question: What is the last name of the person who is convinced of someone's innocence?

Answer:
Alcot.
