"The Show Must Go On" is a song by the English rock band Queen, featured as the twelfth and final track on their 1991 album Innuendo. It is credited to Queen, but written mainly by Brian May. The song chronicles the effort of Freddie Mercury continuing to perform despite approaching the end of his life; he was dying from complications due to AIDS, although his illness had not yet been made public in spite of ongoing media speculation claiming that he was seriously ill. Mercury was so ill, and could barely walk, when the band recorded the song in 1990, that May had concerns as to whether he was physically capable of singing it. Recalling Mercury's performance, May states; "he went in and killed it, completely lacerated that vocal".
It was released as a single in the United Kingdom on 14 October 1991 in promotion for the Greatest Hits II album, just six weeks before Mercury died. Following Mercury's death on 24 November 1991, the song re-entered the British charts and spent as many weeks in the top 75 (five) as it did upon its original release, initially reaching a peak of 16. A live version with Elton John on vocals appeared on Queen's Greatest Hits III album.
The song was first played live on 20 April 1992, during The Freddie Mercury Tribute Concert, performed by the three remaining members of Queen, with Elton John singing lead vocals and Black Sabbath guitarist Tony Iommi playing rhythm guitar.
