Problem: The Rolling Stones are an English rock band formed in London, England in 1962. The first stable line-up consisted of Brian Jones (guitar, harmonica), Mick Jagger (lead vocals), Keith Richards (guitar, backing vocals), Bill Wyman (bass), Charlie Watts (drums), and Ian Stewart (piano). Stewart was removed from the official line-up in 1963 but continued as a touring member until his death in 1985. Jones left the band less than a month before his death in 1969, having already been replaced by Mick Taylor, who remained until 1974.

Before leaving Atlantic, the Rolling Stones released Undercover (UK 3; US 4) in late 1983. Despite good reviews and the Top Ten peak position of the title track, the record sold below expectations and there was no tour to support it. Subsequently, the Stones' new marketer/distributor CBS Records took over distributing the Stones' Atlantic catalogue. By this time, the Jagger/Richards rift had grown significantly. To Richards' annoyance, Jagger had signed a solo deal with CBS Records, and he spent much of 1984 writing songs for his first album. He also declared his growing lack of interest in the Rolling Stones. By 1985, Jagger was spending more time on solo recordings, and much of the material on 1986's Dirty Work was generated by Richards, with more contributions by Wood than on previous Rolling Stones albums. The album was recorded in Paris, and Jagger was often absent from the studio, leaving Richards to keep the recording sessions moving forward. In June 1985, Jagger teamed up with David Bowie for "Dancing in the Street", which was recorded as part of the Live Aid charity movement. This was one of Jagger's first solo performances, and the song reached No. 1 in the UK, and No. 7 in the US. In December 1985, Stewart died of a heart attack. The Rolling Stones played a private tribute concert for him at London's 100 Club in February 1986, two days before they were presented with a Grammy Lifetime Achievement Award. Dirty Work (UK No. 4; US No. 4) was released in March 1986 to mixed reviews despite the presence of the US Top Five hit "Harlem Shuffle". With relations between Richards and Jagger at a low, Jagger refused to tour to promote the album, and instead undertook his own solo tour, which included Rolling Stones songs. As a result of the animosity within the band during this period, they almost broke up. Jagger's solo records, She's the Boss (UK 6; US 13) (1985) and Primitive Cool (UK 26; US 41) (1987), met with moderate success, and in 1988, with the Rolling Stones mostly inactive, Richards released his first solo album, Talk Is Cheap (UK 37; US 24). It was well received by fans and critics, going gold in the US. Richards has subsequently referred to this late-80s period, where the two were recording solo albums with no obvious reunion of the Stones in sight, as "World War III". The following year 25x5: The Continuing Adventures of the Rolling Stones, a documentary spanning the career of the band was released for their 25th anniversary.

Problem: Richard was born on 2 October 1452 at Fotheringhay Castle, the twelfth of thirteen children of Richard Plantagenet, 3rd Duke of York and Cecily Neville at the beginning of what has traditionally been labelled the "Wars of the Roses", a period of "three or four decades of political instability and periodic open civil war in the second half of the fifteenth century", between supporters of Richard's father (a potential claimant to the throne of King Henry VI from birth)--"Yorkists"--in opposition to the regime of Henry VI and his wife, Margaret of Anjou, and those loyal to the crown ("Lancastrians"). When his father and the Nevilles were forced to flee to Ludlow in 1459, Richard and his older brother, George (later Duke of Clarence), were placed in the custody of the Duchess of Buckingham, and the Archbishop of Canterbury. When his father and elder brother Edmund, Earl of Rutland, were killed at the Battle of Wakefield on 30 December 1460, Richard, who was eight years old, and George were sent by his mother, the Duchess of York, to the Low Countries. They returned to England following the defeat of the Lancastrians at the Battle of Towton and participated in the coronation of Richard's eldest brother as King Edward IV in June 1461.

Apart from Shakespeare, Richard appears in many other works of literature. Two other plays of the Elizabethan era predated Shakespeare's work. The Latin-language drama Richardus Tertius (first known performance in 1580) by Thomas Legge is believed to be the first history play written in England. The anonymous play The True Tragedy of Richard III (c. 1590), performed in the same decade as Shakespeare's work, was probably an influence on Shakespeare. Neither of the two plays places any emphasis on Richard's physical appearance, though the True Tragedy briefly mentions that he is "A man ill shaped, crooked backed, lame armed" adding that he is "valiantly minded, but tyrannous in authority". Both portray him as a man motivated by personal ambition, who uses everyone around him to get his way. Ben Jonson is also known to have written a play Richard Crookback in 1602, but it was never published and nothing is known about its portrayal of the king. Marjorie Bowen's 1929 novel Dickon set the trend for pro-Ricardian literature. Particularly influential was The Daughter of Time (1951) by Josephine Tey, in which a modern detective concludes that Richard III is innocent in the death of the Princes. Other novelists such as Valerie Anand in the novel Crown of Roses (1989) have also offered alternative versions to the theory that he murdered them. Sharon Kay Penman, in her historical novel The Sunne in Splendour, attributes the death of the Princes to the Duke of Buckingham. In the mystery novel The Murders of Richard III by Elizabeth Peters (1974) the central plot revolves around the debate as to whether Richard III was guilty of these and other crimes. A sympathetic portrayal of Richard III is given in The Founding, the first volume in The Morland Dynasty series by Cynthia Harrod-Eagles. One film adaptation of Shakespeare's play Richard III is the 1955 version directed and produced by Laurence Olivier, who also played the lead role. Also notable are the 1995 film version starring Ian McKellen, set in a fictional 1930s fascist England, and Looking for Richard, a 1996 documentary film directed by Al Pacino, who plays the title character as well as himself. The play has been adapted for television on several occasions.
