Question: In what year did the singer of Living on My Own 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: 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 3: The Solo Collection: The Solo Collection is a box set detailing the solo career of Freddie Mercury; it includes the material Mercury recorded before joining up with Queen, up through the 1993 No More Brothers remixes. Mercury's singles and two studio albums are included, as well as a disc of instrumentals, numerous rare tracks, and a set of interviews conducted by David Wigg. Also included are two DVDs: a collection of music videos, and a documentary covering Mercury's life.
Document 4: 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 9: 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).
Document 10: 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 11: 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.

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 15: I Was Born to Love You (song): "I Was Born to Love You" is a 1985 song by Freddie Mercury, and was released as a single and on the "Mr. Bad Guy" album.

The Queen version from the "Made in Heaven" album also includes samples of Mercury's ad-lib vocals taken from "A Kind of Magic" and from "Living on My Own".
