Passage: Lennon met Cynthia Powell (1939–2015) in 1957, when they were fellow students at the Liverpool College of Art. Although Powell was intimidated by Lennon's attitude and appearance, she heard that he was obsessed with the French actress Brigitte Bardot, so she dyed her hair blonde. Lennon asked her out, but when she said that she was engaged, he screamed out, "I didn't ask you to fuckin' marry me, did I?" She often accompanied him to Quarrymen gigs and travelled to Hamburg with McCartney's girlfriend to visit him. Lennon was jealous by nature and eventually grew possessive, often terrifying Powell with his anger and physical violence. Lennon later said that until he met Ono, he had never questioned his chauvinistic attitude toward women. He said that the Beatles song "Getting Better" told his own story, "I used to be cruel to my woman, and physically – any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace."Recalling his July 1962 reaction when he learned that Cynthia was pregnant, Lennon said, "There's only one thing for it Cyn. We'll have to get married." The couple wed on 23 August at the Mount Pleasant Register Office in Liverpool, with Brian Epstein serving as best man. His marriage began just as Beatlemania was taking off across the UK. He performed on the evening of his wedding day and would continue to do so almost daily from then on. Epstein feared that fans would be alienated by the idea of a married Beatle, and he asked the Lennons to keep their marriage secret. Julian was born on 8 April 1963; Lennon was on tour at the time and did not see his infant son until three days later.Cynthia attributed the start of the marriage breakdown to Lennon's use of LSD, and she felt that he slowly lost interest in her as a result of his use of the drug. When the group travelled by train to Bangor, Wales in 1967 for the Maharishi Yogi's Transcendental Meditation seminar, a policeman did not recognise her and stopped her from boarding. She later recalled how the incident seemed to symbolise the end of their marriage. After Cynthia arrived home at Kenwood, she found Lennon with Ono and left the house to stay with friends. Alexis Mardas later claimed to have slept with her that night, and a few weeks later he informed her that Lennon was seeking a divorce and custody of Julian on the grounds of her adultery with him. After negotiations, Lennon capitulated and agreed to let her divorce him on the same grounds. The case was settled out of court in November 1968, with Lennon giving her £100,000 ($240,000 in US dollars at the time), a small annual payment and custody of Julian. 
Question: What is the first name of the child of the person that began to use LSD and lose interest in his wife?

Ex Output:
Julian.

Passage: Between 9:00 pm and 10:00 pm the guards enacted a strategy whereby the police officers, backed by the bayonets of the soldiers, advanced to the crowd and arrested each a man, who was then taken into the station, disarmed, and held there. The strategy was largely successful, and by 11:00 pm the area around the station was mostly cleared, though sporadic gunfire could be heard throughout the night. Between 165 and 200 were detained in total, and the most violent of the captives were removed and taken to the police station. The news reported that four, including one police officer, were injured in the exchange, and several who resisted arrest were beaten severely.At the foundry near the Carey Street Bridge, a crowd of more than 100 gathered and threatened to set fire to the area. A contingent of the 5th under Captain Lipscomb arrived, and a volley fired over the heads of the crowd was sufficient to dissuade the crowd. An unsuccessful attempt was also made to burn a B&O transportation barge at Fell's Point. The news reported that 16 were arrested in a confrontation between citizens and the police at Lee and Eutaw, and that during the night, three separate attempts were made to set fire the 6th Regiment armory, but all were frustrated by the remaining garrison there.Just before midnight, 120–135 marines arrived at the station and reported to the governor, who ordered them to set about capturing the leaders of the mob. Governor Carroll telegraphed and advised President Hayes that order had been restored in the city.
Between 2:00 am and 3:00 am on Sunday morning, July 22, the peace was again broken and fire alarms began to ring throughout the city. To the west, at the Mount Clare Shops of the B&O, a 37-car train of coal and oil had been set on fire. Police, firefighters, and thousands of citizens flocked to the scene. A contingent of 50 marines was dispatched to the area to provide assistance. The cars which had not yet caught fire were detached from those burning, and by the time the flames were extinguished between seven and nine cars had been burned. Between $11,000 and $12,000 in damage was sustained.At 4:00 am another alarm sounded: the planing mills and lumber yard of J. Turner & Cate near the Philadelphia Wilmington & Baltimore rail depot, had been set on fire. The entire property, extending over a full city block, was destroyed. Realizing the severity of the situation, the firefighters concentrated their efforts on trying to save the surrounding structures.According to news reports, the first passenger trains left the city at 9:00 am, and continued running throughout the day. Around 10:00 am, General W. S. Hancock arrived and was followed by 360–400 federal troops from New York and Fort Monroe, who relieved those guarding Camden Station. They brought with them two 12 pounder artillery pieces. From that point on, the men of the 5th and the federal troops took turns guarding the station. 
Question: At what time was the lumber yard of J. Turner & Cate set on fire on the day where a car train of coal was set on fire?

Ex Output:
4:00 am.

Passage: By September 1963, Waters and Mason had lost interest in their studies and moved into the lower flat of Stanhope Gardens, owned by Mike Leonard, a part-time tutor at the Regent Street Polytechnic. Waters, Mason and Wright first played music together in late 1963, in a band formed by vocalist Keith Noble and bassist Clive Metcalfe. They usually called themselves Sigma 6, but also used the name the Meggadeaths. Waters played rhythm guitar and Mason played drums, Wright played any keyboard he could arrange to use, and Noble's sister Sheilagh provided occasional vocals. In the early years the band performed during private functions and rehearsed in a tearoom in the basement of Regent Street Polytechnic.When Metcalfe and Noble left to form their own group in September 1963, the remaining members asked Barrett and guitarist Bob Klose to join. Waters switched to the bass and by January 1964, the group became known as the Abdabs, or the Screaming Abdabs. During late 1964, the band used the names Leonard's Lodgers, Spectrum Five, and eventually, the Tea Set. Sometime during late 1965, the Tea Set began calling itself the Pink Floyd Sound, later the Pink Floyd Blues Band and by early 1966, Pink Floyd.By early 1966, Barrett was Pink Floyd's frontman, guitarist, and songwriter. He wrote or co-wrote all but one track of their debut LP The Piper at the Gates of Dawn, released in August 1967. Waters contributed the song "Take Up Thy Stethoscope and Walk" (his first sole writing credit) to the album. By late 1967, Barrett's deteriorating mental health and increasingly erratic behaviour, rendered him "unable or unwilling" to continue in his capacity as Pink Floyd's singer-songwriter and lead guitarist. In early March 1968 Pink Floyd met with managers Peter Jenner and Andrew King of Blackhill Enterprises to discuss the band's future. Barrett agreed to leave Pink Floyd, and the band "agreed to Blackhill's entitlement in perpetuity" regarding "past activities". The band's new manager Steve O'Rourke made a formal announcement about the departure of Barrett and the arrival of David Gilmour in April 1968. 
Question: What is the name of the person who wrote or co-wrote all but one track of the debut LP The Piper at the Gates of Dawn, released in August 1967?

Ex Output:

Barrett.
