input: During 1979, the band began to attract a live following in London, being regulars at the Dublin Castle in Camden Town. The band's first commercial recording was the Lee Thompson composition "The Prince". The song, like the band's name, paid homage to their idol, Prince Buster. The song was released through 2 Tone Records, the label of The Specials founder Jerry Dammers. The song was a surprise hit, peaking in the UK music charts at number 16. A performance of "The Prince" on popular UK music show Top of the Pops helped Madness gain public recognition. Madness then toured with fellow 2 Tone bands The Specials and The Selecter, before recording their debut album.  That debut album, One Step Beyond... was released by Stiff Records. The album included a re-recording of "The Prince" and its B-side "Madness", and the band's second and third singles: "One Step Beyond" and "My Girl". The title song was a cover of the B-side of the 1960s Prince Buster hit "Al Capone". One Step Beyond... stayed in the British charts for 78 weeks, peaking at number 2. After the release of "My Girl", the band felt that they had exhausted the material from One Step Beyond..., and did not want to release any more singles from the album. However, Dave Robinson, head of Stiff Records, disagreed. Eventually, a compromise was made, and the band decided to release an EP featuring one album track and three new tracks. The result was the Work Rest and Play EP, which was headlined by the song "Night Boat to Cairo", from the One Step Beyond album. The EP reached number 6 in the UK singles chart.  Live recordings of Madness performances as well as those by other 2 Tone bands were used in the documentary film and soundtrack album Dance Craze.  In 1980, the band's second album, Absolutely reached number 2 in the UK album charts. Absolutely spawned some of the band's biggest hits, most notably "Baggy Trousers", which peaked at number 3 in the UK singles chart. "Embarrassment" reached number 4 in the charts, and the instrumental song "The Return of the Los Palmas 7" climbed to number 7. Although the album reviews were generally less enthusiastic than those of One Step Beyond..., they were mostly positive. Robert Christgau gave the album a favourable B- grade, but Rolling Stone awarded the album just one out of five stars. Rolling Stone was particularly scathing of the ska revival in general, stating that "The Specials wasn't very good" and Madness were simply "the Blues Brothers with English accents".  A drama-documentary film entitled Take It or Leave It was released in 1981, featuring the band members playing themselves in a re-creation of their early days to the then-current period.

Problem: Background: Legion (David Charles Haller) is a fictional superhero appearing in American comic books published by Marvel Comics. He is the mutant son of Professor Charles Xavier and Gabrielle Haller. Legion takes the role of an antihero who has a severe mental illness including a form of dissociative identity disorder, in which each of his alternate personas controls one of his many superpowers. The television series Legion premiered on FX network in 2017.
Context: When Mystique tracked down David years later to get revenge for "his" murder of Destiny, he awakened with his fractured mind healed. David had a new goal, to help his father realize his dream of human-mutant coexistence by killing Magneto, Xavier's greatest opponent, before he had a chance to amass power. He traveled twenty years into the past, when Xavier and Magneto were orderlies at the mental hospital. In the process, he loses his memory. Magneto then accidentally triggers his memory, causing David to go on a rampage, attacking Magneto and revealing the existence of mutants to the public decades too early. Several X-Men who were pulled back in time with him were unable to prevent him from attacking Magneto. Xavier, however, leaped into the path of the psi-knife (the focused totality of Legion's psionic powers) and was killed in Magneto's place, causing the formation of the Age of Apocalypse timeline.  Due to being trapped in the past by David's actions, Bishop enlisted the aid of the new reality's X-Men to travel back in time to confront Legion again. Bishop seized Legion's psi-blade and drove it into his own chest, allowing Legion to see the future that he caused. In his last moments, David apologized for what he did. David's mother, Gabrielle Haller, described having a "maternal loss" afterward, implying she miscarried before giving birth to David.  While David was considered deceased, some of his alternate personalities remained trapped between life and death, manifesting as spirits. When the spirits started terrorizing Israel, Excalibur was called to stop them. After learning that the spirits were refusing death, Meggan used her empathy to calm their rage, convincing them to go "towards the light."

Question: Hubert Neal McGaughey Jr. was born on July 30, 1958, in Jacksonville, Texas, to a Filipina American mother and Irish-American father. Inspired by the variety of music that his parents listened to, which included country, rock, disco and R&B, McGaughey first sang in his church choir before founding an R&B band. He later switched his focus to country music, performing in various bars and clubs in Texas. McGaughey, after attending junior college near his hometown, found work selling shoes at a shopping mall.

He then signed to Atlantic Records in 1990, changing his surname to McCoy per the label's request, as fans had already begun to refer to him as McCoy. His debut album, At This Moment, was released that year. None of the three singles made the country Top 40, although the lead-off single "If I Built You a Fire" was a Top 20 country hit in Canada. The other two releases were the title track, a cover of Billy Vera and the Beaters' hit song from 1987, and "This Time I've Hurt Her More Than She Loves Me", which was co-written by Earl Thomas Conley and originally recorded by Conway Twitty. McCoy continued touring and developed a "reputation for exciting, freewheeling live shows."  A second album for Atlantic, Where Forever Begins, followed in 1992. This album produced his first American Top 40 country hit in its No. 40-peaking title track, followed by "There Ain't Nothin' I Don't Like About You" at No. 57, and "Now I Pray for Rain" at No. 26. The album was also his first entry on Top Country Albums, at No. 58.  Working with producer Barry Beckett for the first time, McCoy released No Doubt About It in 1994. The album produced his only number 1 country hits in its title track and "Wink", both of which also made minor entries on the Billboard Hot 100. The album also earned a platinum certification from the Recording Industry Association of America (RIAA) and gold certification from the Canadian Recording Industry Association (CRIA). Its final single was "The City Put the Country Back in Me" at No. 5.
