Context paragraphs:
We Will Rock You (video): We Will Rock You is a concert film by English band Queen.  It was filmed in Montreal, Quebec, Canada at the Montreal Forum on 24 and 25 November 1981, ten years to the day before lead singer Freddie Mercury's death from AIDS.

The Freddie Mercury Tribute Concert: The Freddie Mercury Tribute Concert for AIDS Awareness was a benefit concert held on Easter Monday, 20 April 1992 at Wembley Stadium in London, England for an audience of 72,000.  The concert was produced for television by Ray Burdis and broadcast live on television and radio to 76 countries around the world, with an audience of up to one billion.  The concert was a tribute to the life of Queen lead vocalist, Freddie Mercury, with proceeds going to AIDS research.  The show marked bassist John Deacon's final full-length concert with Queen (save a short live appearance with Brian May, Roger Taylor and Elton John in 1997).  The profits from the concert were used to launch The Mercury Phoenix Trust, an AIDS charity organisation.

Hungarian Rhapsody: Queen Live in Budapest: Hungarian Rhapsody: Queen Live in Budapest is a concert film of the British rock band Queen's performance in Budapest on 27 July 1986.  It was part of Brian May, Roger Taylor and John Deacon's final tour with original lead singer Freddie Mercury, The Magic Tour.  Queen were one of the few bands from Western Europe to perform in the Eastern Bloc during the Cold War.  The film had a limited release in theatres worldwide on 20 September 2012.  The concert was released on DVD and Blu-ray for the first time on 5 November 2012 worldwide, except in the United States where it was released a day later.  The concert title is a play on the Hungarian Rhapsodies by Franz Liszt and one of Queen's most celebrated hits, "Bohemian Rhapsody."

Lazing on a Sunday Afternoon: "Lazing on a Sunday Afternoon" is a song by the British rock band Queen, originally released on their fourth album "A Night at the Opera" in 1975.  It is one of five contributions by Freddie Mercury to the band's 1975 album.

Death on Two Legs (Dedicated to...): "Death on Two Legs (Dedicated to...)" is a song by the British rock band Queen, and is the opening track on their fourth album "A Night at the Opera".  The song was written by Freddie Mercury and allegedly describes his hatred of Queen's original manager, the late Norman Sheffield, who is reputed to have mistreated the band and abused his managerial role from 1972 to 1975.  Roger Taylor also noted that despite the success of "Killer Queen" and "Sheer Heart Attack", the album preceding "A Night at the Opera", the band was broke before the album was made.

Magic Tour (Queen): The Magic Tour was the biggest and final tour by the British rock band Queen with their lead singer Freddie Mercury and their bass guitarist John Deacon, which took place in 1986.  The band would not tour again until 19 years later, when the Queen + Paul Rodgers Tour began in 2005, after the death of Freddie Mercury on 24 November 1991, and the retirement of John Deacon in 1997.  The Magic Tour took in 26 dates around Europe's stadiums, in support of their then latest album "A Kind of Magic".

Bohemian Rhapsody: "Bohemian Rhapsody" is a song by the British rock band Queen.  It was written by Freddie Mercury for the band's 1975 album "A Night at the Opera".  It is a six-minute suite, consisting of several sections without a chorus: an intro, a ballad segment, an operatic passage, a hard rock part and a reflective coda.  The song is a more accessible take on the 1970s progressive rock genre.  It was reportedly the most expensive single ever made at the time of its release, though the exact cost of production cannot be determined.

The Invisible Man (Queen song): "The Invisible Man" is a song by the British rock band Queen, written by drummer Roger Taylor but credited to Queen.  The song is sung mostly by Freddie Mercury, with vocal contributions from Taylor.  Originally released on the album "The Miracle", it was released as a single in 1989.  Taylor claims that he got the inspiration to create the song while reading a book (possibly the book of the same name), and the bassline instantly came to his imagination.  This song marks the only time in any of Queen's songs that all four band members names are mentioned in the lyrics.  The first being Freddie Mercury, followed by John Deacon.  Brian May's name is then said twice (just before his guitar solo starts), and while saying "Roger Taylor", the first "r" is rolled to emulate the drums at the end of the verse.  Freddie Mercury's name is said by drummer Roger Taylor, and the other ones by the lead singer Freddie Mercury.

Too Much Love Will Kill You: "Too Much Love Will Kill You" is a song written by British guitarist Brian May of Queen, Frank Musker, and Elizabeth Lamers.  The song reflected the breakdown of May's first marriage and attraction to his future wife, Anita Dobson.  It was first recorded by Queen around 1988 or before, and was intended to be on the band's "The Miracle" album in 1989, but did not make the cut due to legal disputes following the band's decision that all songs on the album would be written by the group as opposed to individuals.  After Freddie Mercury's death in 1991, May arranged a solo version, which he performed at the Freddie Mercury Tribute Concert in 1992, and subsequently included on his solo album "Back to the Light" that same year.  Released as a single, it reached No. 5 on the UK Singles Chart.  Because it was first played publicly at The Freddie Mercury Tribute Concert, a common misconception is that it was written as a tribute to Freddie Mercury, although it had actually been written several years before he died.

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.
