Question: When was the band who performed Dancing on the Valentine established?

full_context: Document 1: Duran Duran: Duran Duran () are an English new wave band formed in Birmingham in 1978. The band were one of the most successful acts of the 1980s, but by the end of the decade, membership and music style changes challenged the band before a resurgence in the early 1990s. The group were a leading band in the MTV-driven Second British Invasion of the US in the 1980s. They achieved 14 singles in the top 10 of the UK Singles Chart and 21 in the US "Billboard" Hot 100, and have sold over 100 million records worldwide.
Document 2: LaserDisc: There were also 12 cm (4.7 in) (CD size) "single"-style discs produced that were playable on LaserDisc players. These were referred to as CD Video (CD-V) discs, and Video Single Discs (VSD). A CD-V carried up to five minutes of analog LaserDisc-type video content (usually a music video), as well as up to 20 minutes of digital audio CD tracks. The original 1989 release of David Bowie's retrospective Sound + Vision CD box set prominently featured a CD-V video of Ashes to Ashes, and standalone promo CD-Vs featured the video, plus three audio tracks: "John, I'm Only Dancing", "Changes", and "The Supermen".
Document 3: Carnival (EP): Carnival is a dance music EP by Duran Duran, originally released in various markets around the world in September 1982 by EMI.
Document 4: Seven and the Ragged Tiger: Seven and the Ragged Tiger is the third studio album by English new wave band Duran Duran. It was released on 21 November 1983 by EMI. It was the band's first and only number one album on the UK Albums Chart, and would prove to be the last studio album for the band's most famous line-up until 2004's "Astronaut".
Document 5: Dancing in the Dark (Bruce Springsteen song): Directed by Brian De Palma, the video was shot at the Saint Paul Civic Center in Saint Paul, Minnesota, on June 28 and 29, 1984. The first night was a pure video shot, the second was on the opening date of the Born in the U.S.A. Tour. Bruce Springsteen and the E Street Band performed the song twice during that show to allow Brian De Palma to get all the footage he needed. The video is a straight performance video, with Springsteen not playing a guitar, allowing him to invite a young woman from the audience, performed by Courteney Cox, to dance along with him on the stage at the end. In September 1985, the video won the MTV Video Music Award for Best Stage Performance.
Document 6: Post-punk: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.

Document 9: Hard rock: Established bands made something of a comeback in the mid-1980s. After an 8-year separation, Deep Purple returned with the classic Machine Head line-up to produce Perfect Strangers (1984), which reached number five in the UK, hit the top five in five other countries, and was a platinum-seller in the US. After somewhat slower sales of its fourth album, Fair Warning, Van Halen rebounded with the Top 3 album Diver Down in 1982, then reached their commercial pinnacle with 1984. It reached number two on the Billboard album chart and provided the track "Jump", which reached number one on the singles chart and remained there for several weeks. Heart, after floundering during the first half of the decade, made a comeback with their eponymous ninth studio album which hit number one and contained four Top 10 singles including their first number one hit. The new medium of video channels was used with considerable success by bands formed in previous decades. Among the first were ZZ Top, who mixed hard blues rock with new wave music to produce a series of highly successful singles, beginning with "Gimme All Your Lovin'" (1983), which helped their albums Eliminator (1983) and Afterburner (1985) achieve diamond and multi-platinum status respectively. Others found renewed success in the singles charts with power ballads, including REO Speedwagon with "Keep on Loving You" (1980) and "Can't Fight This Feeling" (1984), Journey with "Don't Stop Believin'" (1981) and "Open Arms" (1982), Foreigner's "I Want to Know What Love Is", Scorpions' "Still Loving You" (both from 1984), Heart’s "What About Love" (1985) and "These Dreams" (1986), and Boston's "Amanda" (1986).
Document 10: Second British Invasion: During the Second British Invasion, established British acts such as Queen, David Bowie, Paul McCartney, Phil Collins, Rod Stewart and Elton John saw their popularity increase; a few acts that dated to the era of the original British Invasion, including George Harrison, Eddy Grant, The Hollies and The Moody Blues, had their last major hits in this time frame. Counting his work with Genesis, Collins had more top 40 hits on the Billboard Hot 100 chart during the 1980s than any other artist.
Document 11: Hard rock: Bon Jovi's third album, Slippery When Wet (1986), mixed hard rock with a pop sensitivity and spent a total of 8 weeks at the top of the Billboard 200 album chart, selling 12 million copies in the US while becoming the first hard rock album to spawn three top 10 singles — two of which reached number one. The album has been credited with widening the audiences for the genre, particularly by appealing to women as well as the traditional male dominated audience, and opening the door to MTV and commercial success for other bands at the end of the decade. The anthemic The Final Countdown (1986) by Swedish group Europe was an international hit, reaching number eight on the US charts while hitting the top 10 in nine other countries. This era also saw more glam-infused American hard rock bands come to the forefront, with both Poison and Cinderella releasing their multi-platinum début albums in 1986. Van Halen released 5150 (1986), their first album with Sammy Hagar on lead vocals, which was number one in the US for three weeks and sold over 6 million copies. By the second half of the decade, hard rock had become the most reliable form of commercial popular music in the United States.
Document 12: Waltz Darling: Waltz Darling is the fourth studio album by Malcolm McLaren (his only with The Bootzilla Orchestra), released in 1989.

Another single, "House of the Blue Danube" was used in the trailer for the 1990 film, "Teenage Mutant Ninja Turtles".
