Question: In what year did the lyricist of It's A Hard Life die?

full_context: Document 1: Queen (band): Before forming Queen, Brian May and Roger Taylor had played together in a band named Smile. Freddie Mercury (then known by his birth name of Farrokh "Freddie" Bulsara) was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. Mercury joined the band in 1970, suggested "Queen" as a new band name, and adopted his familiar stage name. John Deacon was recruited prior to recording their eponymous debut album in 1973. Queen first charted in the UK with their second album, Queen II, in 1974, but it was the release of Sheer Heart Attack later that year and A Night at the Opera in 1975 which brought them international success. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK for nine weeks and popularised the music video. Their 1977 album, News of the World, contained "We Will Rock You" and "We Are the Champions", which have become anthems at sporting events. By the early 1980s, Queen were one of the biggest stadium rock bands in the world. Their performance at 1985's Live Aid is ranked among the greatest in rock history by various music publications, with a 2005 industry poll ranking it the best. In 1991, Mercury died of bronchopneumonia, a complication of AIDS, and Deacon retired in 1997. Since then, May and Taylor have occasionally performed together, including with Paul Rodgers (2004–09) and with Adam Lambert (since 2011). In November 2014, Queen released a new album, Queen Forever, featuring vocals from the late Mercury.
Document 2: Crazy Little Thing Called Love: ``Crazy Little Thing Called Love ''is a song by the British rock band Queen. Written by Freddie Mercury in 1979, the track is featured on their 1980 album The Game, and also appears on the band's compilation album, Greatest Hits in 1981. The song peaked at number two in the UK Singles Chart in 1979, and became the group's first number - one single on the Billboard Hot 100 in the US in 1980, remaining there for four consecutive weeks. It topped the Australian ARIA Charts for seven weeks.
Document 3: It's a Hard Life: "It's a Hard Life" is a song by the British rock band Queen, written by lead singer Freddie Mercury. It was featured on their 1984 album "The Works", and it was the third single from that album. It reached number 6 in the UK Singles Chart and was their third consecutive Top 10 single from the album. It also reached number 2 in Ireland and number 20 in the Netherlands. It also came 19th on a poll, The Nation's Favourite Queen Song broadcast on ITV on Tuesday 11 November 2014.
Document 4: Queen (band): On 25 and 26 April, May and Taylor appeared on the eleventh series of American Idol at the Nokia Theatre, Los Angeles, performing a Queen medley with the six finalists on the first show, and the following day performed "Somebody to Love" with the 'Queen Extravaganza' band. Queen were scheduled to headline Sonisphere at Knebworth on 7 July 2012 with Adam Lambert before the festival was cancelled. Queen's final concert with Freddie Mercury was in Knebworth in 1986. Brian May commented, "It's a worthy challenge for us, and I'm sure Adam would meet with Freddie's approval." Queen expressed disappointment at the cancellation and released a statement to the effect that they were looking to find another venue. It was later announced that Queen + Adam Lambert would play two shows at the Hammersmith Apollo, London on 11 and 12 July 2012. Both shows sold out within 24 hours of tickets going on open sale. A third London date was scheduled for 14 July. On 30 June, Queen + Lambert performed in Kiev, Ukraine at a joint concert with Elton John for the Elena Pinchuk ANTIAIDS Foundation. Queen also performed with Lambert on 3 July 2012 at Moscow's Olympic Stadium, and on 7 July 2012 at the Municipal Stadium in Wroclaw, Poland.
Document 5: Queen (band): In 1997, Queen returned to the studio to record "No-One but You (Only the Good Die Young)", a song dedicated to Mercury and all those that die too soon. It was released as a bonus track on the Queen Rocks compilation album later that year. In January 1997, Queen performed "The Show Must Go On" live with Elton John and the Béjart Ballet in Paris on a night Mercury was remembered, and it marked the last performance and public appearance of John Deacon, who chose to retire. The Paris concert was only the second time Queen had played live since Mercury's death, prompting Elton John to urge them to perform again.
Document 6: Queen (band): Queen are a British rock band formed in London in 1970. Their classic line-up was Freddie Mercury (lead vocals and piano), Brian May (lead guitar and vocals), Roger Taylor (drums and vocals) and John Deacon (bass guitar). Their earliest works were influenced by progressive rock, hard rock and heavy metal, but the band gradually ventured into more conventional and radio-friendly works by incorporating further styles, such as arena rock and pop rock.
Document 7: Crazy Little Thing Called Love: ``Crazy Little Thing Called Love ''is a song by the British rock band Queen. Written by Freddie Mercury in 1979, the track is included on their 1980 album The Game, and also appears on the band's compilation album, Greatest Hits in 1981. The song peaked at number two in the UK Singles Chart in 1979, and became the group's first number - one single on the Billboard Hot 100 in the US in 1980, remaining there for four consecutive weeks. It topped the Australian ARIA Charts for seven weeks.
Document 8: Queen (band): The band had a number of bass players during this period who did not fit with the band's chemistry. It was not until February 1971 that they settled on John Deacon and began to rehearse for their first album. They recorded four of their own songs, "Liar", "Keep Yourself Alive", "The Night Comes Down" and "Jesus", for a demo tape; no record companies were interested. It was also around this time Freddie changed his surname to "Mercury", inspired by the line "Mother Mercury, look what they've done to me" in the song "My Fairy King". On 2 July 1971, Queen played their first show in the classic line-up of Mercury, May, Taylor and Deacon at a Surrey college outside London.
Document 9: Queen (band): At the end of 2004, May and Taylor announced that they would reunite and return to touring in 2005 with Paul Rodgers (founder and former lead singer of Free and Bad Company). Brian May's website also stated that Rodgers would be "featured with" Queen as "Queen + Paul Rodgers", not replacing Mercury. The retired John Deacon would not be participating. In November 2004, Queen were among the inaugural inductees into the UK Music Hall of Fame, and the award ceremony was the first event at which Rodgers joined May and Taylor as vocalist.
Document 10: Love of My Life (Queen song): ``Love of My Life ''is a ballad by the British rock band Queen from their 1975 album A Night at the Opera. The song was written by Freddie Mercury about Mary Austin, with whom he had a long term relationship in the early 1970s. After performing the song in South America in 1981, the version from their live album Live Killers reached number 1 in the singles chart in Argentina and Brazil, and stayed in the charts in Argentina for an entire year.
Document 11: Don't Stop Me Now: ``Do n't Stop Me Now ''is a song by the British rock band Queen, featured on their 1978 album Jazz that was released as a single in 1979. Written by lead singer Freddie Mercury, it was recorded in August 1978 at Super Bear Studios in Berre - les - Alpes (Alpes - Maritimes), France, and is the twelfth track on the album.
Document 12: Queen (band): Innuendo was released in early 1991 with an eponymous number 1 UK hit and other charting singles including, "The Show Must Go On". Mercury was increasingly ill and could barely walk when the band recorded "The Show Must Go On" in 1990. Because of this, May had concerns about whether he was physically capable of singing it. Recalling Mercury's successful performance May states; "he went in and killed it, completely lacerated that vocal". The rest of the band were ready to record when Mercury felt able to come in to the studio, for an hour or two at a time. May says of Mercury: “He just kept saying. 'Write me more. Write me stuff. I want to just sing this and do it and when I am gone you can finish it off.’ He had no fear, really.” The band's second greatest hits compilation, Greatest Hits II, followed in October 1991, which is the eighth best-selling album of all time in the UK and has sold 16 million copies worldwide.
Document 13: Queen (band): In 1978, Queen toured the US and Canada, and spent much of 1979 touring in Europe and Japan. They released their first live album, Live Killers, in 1979; it went platinum twice in the US. Queen also released the very successful single "Crazy Little Thing Called Love", a rockabilly inspired song done in the style of Elvis Presley. The song made the top 10 in many countries, topped the Australian ARIA Charts for seven consecutive weeks, and was the band's first number one single in the United States where it topped the Billboard Hot 100 for four weeks. Having written the song on guitar and played rhythm on the record, Mercury played rhythm guitar while performing the song live, which was the first time he ever played guitar in concert. In December 1979, Queen played the opening night at the Concert for the People of Kampuchea in London, having accepted a request by the event's organiser Paul McCartney.
Document 14: Queen (band): The group's second LP, Queen II, was released in 1974, and features rock photographer Mick Rock's iconic image of the band on the cover. This image would be used as the basis for the 1975 "Bohemian Rhapsody" music video production. The album reached number five on the British album chart and became the first Queen album to chart in the UK. The Freddie Mercury-written lead single "Seven Seas of Rhye" reached number ten in the UK, giving the band their first hit. The album is the first real testament to the band's distinctive layered sound, and features long complex instrumental passages, fantasy-themed lyrics, and musical virtuosity. Aside from its only single, the album also included the song "The March of the Black Queen", a six-minute epic which lacks a chorus. The Daily Vault described the number as "menacing". Critical reaction was mixed; the Winnipeg Free Press, while praising the band's debut album, described Queen II as a "over-produced monstrosity". Allmusic has described the album as a favourite among the band's hardcore fans, and it is the first of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.
Document 15: Queen (band): Brian May and Roger Taylor performed together at several award ceremonies and charity concerts, sharing vocals with various guest singers. During this time, they were billed as Queen + followed by the guest singer's name. In 1998, the duo appeared at Luciano Pavarotti's benefit concert with May performing "Too Much Love Will Kill You" with Pavarotti, later playing "Radio Ga Ga", "We Will Rock You", and "We Are the Champions" with Zucchero. They again attended and performed at Pavarotti's benefit concert in Modena, Italy in May 2003. Several of the guest singers recorded new versions of Queen's hits under the Queen + name, such as Robbie Williams providing vocals for "We Are the Champions" for the soundtrack of A Knight's Tale (2001).
