Input: Consider Input: Passage: The music video for "Single Ladies" was shot immediately after that of "If I Were a Boy", but it received less attention during production than the "higher-gloss, higher-profile video" for "If I Were a Boy". Both videos were shot in black-and-white in New York City and were directed by Jake Nava, with whom Beyoncé had worked on previous music videos including "Crazy in Love" and "Beautiful Liar". "Single Ladies" was choreographed by Frank Gatson Jr. and JaQuel Knight, and incorporates J-Setting choreography. The two music videos premiered on MTV's Total Request Live show on October 13, 2008 to reinforce the concept of conflicting personalities. The videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography, Above and Beyoncé, and the platinum edition of I Am... Sasha Fierce.
Beyoncé told Simon Vozick-Levinson of Entertainment Weekly that the inspiration for the video was a 1969 Bob Fosse routine entitled "Mexican Breakfast" seen on The Ed Sullivan Show, which featured Fosse's wife, Gwen Verdon, dancing with two other women. "Mexican Breakfast" had become an Internet viral sensation the previous summer after Unk's "Walk It Out" was dubbed over the original mix. Beyoncé wanted to attempt a similar dance and eventually, the choreography of "Single Ladies" was liberally adapted from "Mexican Breakfast":
I saw a video on YouTube. [The dancers] had a plain background and it was shot on the crane; it was 360 degrees, they could move around. And I said, 'This is genius.' We kept a lot of the Fosse choreography and added the down-south thing—it's called J-Setting, where one person does something and the next person follows. So it was a strange mixture ... It's like the most urban choreography, mixed with Fosse—very modern and very vintage. 
Question: What  videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography?

Output: Single Ladies.


Input: Consider Input: 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?

Output: Billy Hall.


Input: Consider Input: Passage: In 2006, U2 started work on the follow-up to How to Dismantle an Atomic Bomb (2004), collaborating with producer Rick Rubin. After U2 guitarist the Edge worked individually with Rubin in Los Angeles, the group spent two weeks in September 2006 completing songs with the producer at Abbey Road Studios in London. Later that year, the band released two songs from these sessions on the compilation album U218 Singles: a cover of the Skids' "The Saints Are Coming" with Green Day, and "Window in the Skies". In January 2007, lead singer Bono said U2 intended to take their next album in a different musical direction from their previous few releases. He said, "We're gonna continue to be a band, but maybe the rock will have to go; maybe the rock has to get a lot harder. But whatever it is, it's not gonna stay where it is."Rubin encouraged a "back to basics" approach and wanted the group to bring finished songs to the studio. This approach conflicted with U2's freeform recording style, by which they improvised material in the studio. The Edge said, "we sort of hadn't really finished the songs. It's typical for us, because it's in the process of recording that we really do our writing." Bassist Adam Clayton said, "once we have a song, we're interested in the atmospherics and the tones and the overdubs and the different stuff you can do with it... things that Rick was not in the slightest bit interested in. He was interested in getting it from embryonic stage to a song that could be mixed and put on a record." They ultimately decided to shelve the material recorded with Rubin, but expressed interest in revisiting it in the future. 
Question: What is the last name of the person who was interested in getting it from embryonic stage to a song that could be mixed and put on a record?"?


Output: Rubin.
