Question: Andy Warhol (; born Andrew Warhola; August 6, 1928 - February 22, 1987) was an American artist, director and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966-67). Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator.

In the mid-1960s, Warhol adopted the band the Velvet Underground, making them a crucial element of the Exploding Plastic Inevitable multimedia performance art show. Warhol, with Paul Morrissey, acted as the band's manager, introducing them to Nico (who would perform with the band at Warhol's request). In 1966 he "produced" their first album The Velvet Underground & Nico, as well as providing its album art. His actual participation in the album's production amounted to simply paying for the studio time. After the band's first album, Warhol and band leader Lou Reed started to disagree more about the direction the band should take, and their artistic friendship ended. In 1989, after Warhol's death, Reed and John Cale re-united for the first time since 1972 to write, perform, record and release the concept album Songs for Drella, a tribute to Warhol.  Warhol designed many album covers for various artists starting with the photographic cover of John Wallowitch's debut album, This Is John Wallowitch!!! (1964). He designed the cover art for The Rolling Stones' albums Sticky Fingers (1971) and Love You Live (1977), and the John Cale albums The Academy in Peril (1972) and Honi Soit in 1981. One of Warhol's last works was a portrait of Aretha Franklin for the cover of her 1986 gold album Aretha, which was done in the style of the Reigning Queens series he had completed the year before.  Warhol strongly influenced the new wave/punk rock band Devo, as well as David Bowie. Bowie recorded a song called "Andy Warhol" for his 1971 album Hunky Dory. Lou Reed wrote the song "Andy's Chest", about Valerie Solanas, the woman who shot Warhol, in 1968. He recorded it with the Velvet Underground, and this version was released on the VU album in 1985. Bowie would later play Warhol in the 1996 movie, Basquiat. Bowie recalled how meeting Warhol in real life helped him in the role, and recounted his early meetings with him:  I met him a couple of times, but we seldom shared more than platitudes. The first time we saw each other an awkward silence fell till he remarked my bright yellow shoes and started talking enthusiastically. He wanted to be very superficial. And seemingly emotionless, indifferent, just like a dead fish. Lou Reed described him most profoundly when he once told me they should bring a doll of Andy on the market: a doll that you wind up and doesn't do anything. But I managed to observe him well, and that was a helping hand for the film [Basquiat]. ... We borrowed his clothes from the museum in Pittsburgh, and they were intact, unwashed. Even the pockets weren't emptied: they contained pancake, white, deadly pale fond de teint which Andy always smeared on his face, a check torn in pieces, someone's address, lots of homeopathic pills and a wig. Andy always wore those silver wigs, but he never admitted it were wigs. One of his hairdressers has told me lately that he had his wigs regularly cut, like it were real hair. When the wig was trimmed, he put on another next month as if his hair had grown.

Problem: Ted Arnbjorn Gardestad (Swedish pronunciation: [ted 2jae:de,sta:d]) (18 February 1956 - 22 June 1997) was a Swedish singer, songwriter, musician and actor known internationally as Ted. Gardestad began his acting career in 1966 and began playing music in 1971, signing with Polar Music. Assigned with in-house producers Benny Andersson and Bjorn Ulvaeus,  Gardestad released his first single, "Hela varlden runt," in late 1971 and worked closely with the four members of ABBA to create his debut album Undringar (1972). As Polar Music's best-selling solo artist (aside from ABBA), he continued to work with the group members throughout the 1970s, releasing three more albums Ted (1973), Upptag (1974) and Franska Kort (1976), which were moderately successful.

Shortly after Gardestad's return to Sweden in 1986, the Prime Minister of Sweden, Olof Palme, was murdered. Gardestad was wrongly mentioned in the Swedish media as "the 33-year-old", a suspect in the investigation of the assassination, which severely affected him although Gardestad was on vacation in Greece at the time of the murder, and although he was never questioned by the Swedish police nor was under suspicion by the authorities, the speculations and rumours followed him and his family for the rest of the 1980s. A few years later, he was again the subject of rumours accusing him of being Lasermannen, a bank robber and serial killer. The rumours affected the sensitive and already unstable former star, and Gardestad withdrew and fell into a deep depression.  In the early 1990s, Gardestad was briefly coaxed out of retirement by his friend and fellow Swedish pop singer Harpo. He joined Harpo on a concert tour and made guest appearances. In 1992, they released the duet "Lycka" ("Happiness") as a single; it garnered little attention but marked Gardestad's return to music. Early that year he embarked on his first tour since 1978 and played a series of dates with Plura Jonsson, Tove Naess, Totta Naslund and Dan Hylander, and received overall positive reviews from the press.  In 1993, a compilation album titled Kalendarium 1972-93 was promoted by a tour in the Swedish folkparks; the album and tour were successful, as was his first composition in twelve years, "For karlekens skull" ("For Love's Sake"), which topped the Svensktoppen chart. The Kalendarium collection included a Swedish-language re-recording of the title track from Blue Virgin Isles, "Himlen ar oskyldigt bla" ("The Sky is Innocently Blue"), which fifteen years after its original release became another Svensktoppen hit, and became one of his best-known songs. In early 1994, Kalendarium 1972-93 was awarded a platinum disc. All of Gardestad's albums from the 1970s and early 1980s, with the exception of Blue Virgin Isles, were re-released on CD by Polar, and a generation of Swedes who grew up listening to his music now re-discovered and re-evaluated his back catalogue as adults. His body of work has since come to be regarded as a national treasure as important as those of Evert Taube, Carl Michael Bellman and Cornelis Vreeswijk both by fans and Swedish music critics.
