Background: The Police were a British rock band formed in London in 1977. For most of their history the band consisted of Sting (lead vocals, bass guitar, primary songwriter), Andy Summers (guitar) and Stewart Copeland (drums, percussion). The Police became globally popular in the late 1970s and early 1980s and are generally regarded as one of the first new-wave groups to achieve mainstream success, playing a style of rock influenced by punk, reggae, and jazz. They are also considered one of the leaders of the Second British Invasion of the United States.
Context: During the group's 1983 Shea Stadium concert, Sting felt performing at the venue was "Everest" and decided to pursue a solo career, according to the documentary The Last Play at Shea. After the Synchronicity tour ended in March 1984, the band went on hiatus while Sting recorded and toured in support of his successful solo debut LP, the jazz-influenced The Dream of the Blue Turtles, released in June 1985; Copeland recorded and filmed The Rhythmatist (1985); and Summers recorded another album with Robert Fripp (Bewitched, 1984) and the theme song for the film 2010--which was not used in the film, but included on the soundtrack album. At the 1985 Brit Awards held at London's Grosvenor Hotel on 11 February, the band received the award for Outstanding Contribution to Music. In July the same year, Sting and Copeland participated in Live Aid at Wembley Stadium, London.  In June 1986, the trio reconvened to play three concerts for the Amnesty International A Conspiracy of Hope Tour. In July of that year, they reunited in the studio to record a new album. However, Copeland broke his collarbone in a fall from a horse and was unable to play the drums. As a result of the tense and short-lived reunion in the studio, "Don't Stand So Close to Me '86" was released in October 1986 as their final single and made it into the UK Top 25; it also appeared on the 1986 compilation Every Breath You Take: The Singles, which reached No. 1 in the UK album charts. "De Do Do Do De Da Da Da" was subsequently included on the DTS-CD release of the Every Breath You Take: The Classics album in 1995.  Following the failed effort to record a new studio album, the Police effectively disbanded. In the liner notes to the Police's box set Message in a Box, Summers explains: "The attempt to record a new album was doomed from the outset. The night before we went into the studio Stewart broke his collarbone falling off a horse and that meant we lost our last chance of recovering some rapport just by jamming together. Anyway, it was clear Sting had no real intention of writing any new songs for the Police. It was an empty exercise."
