IN: Mellencamp is of German ancestry. He was born with spina bifida, for which he had corrective surgery as an infant. Mellencamp formed his first band, Crepe Soul, at the age of 14 and later played in the local bands Trash, Snakepit Banana Barn and the Mason Brothers. When Mellencamp was 18, he eloped with his pregnant girlfriend Priscilla Esterline.

Mellencamp participated in the Vote for Change tour in October 2004 leading up to the 2004 U.S. Presidential election. That same month he released the two-disc career hits retrospective Words & Music: John Mellencamp's Greatest Hits, which contained 35 of his radio singles (including all 22 of his Top 40 hits) along with two new tunes, "Walk Tall" and "Thank You" - both produced by Babyface but written by Mellencamp.  In 2005, Mellencamp toured with Donovan and John Fogerty. The first leg of what was called the Words and Music Tour in the spring of 2005 featured Donovan playing in the middle of Mellencamp's set. Mellencamp would play a handful of songs before introducing Donovan and then duetting with him on the 1966 hit "Sunshine Superman". Mellencamp would leave the stage as Donovan played seven or eight of his songs (backed by Mellencamp's band) and then return to finish off his own set after Donovan departed. On the second leg of the tour in the summer of 2005, Fogerty co-headlined with Mellencamp at outdoor amphitheaters across the United States. Fogerty would join Mellencamp for duets on Fogerty's Creedence Clearwater Revival hit "Green River" and Mellencamp's "Rain on the Scarecrow."  Mellencamp released Freedom's Road, his first album of original material in over five years, on January 23, 2007. He intended for Freedom's Road to have a 1960s rock sound while still remaining contemporary, and he feels that goal was achieved. "We wanted to make sure that it had the same feeling of some of the great songs from the '60s but also had the message of today and had the backbeat of today. I think we came up with a pretty timeless sounding album", Mellencamp told his online radio station in late 2006. "Our Country", the first single from Freedom's Road, was played as the opening song on Mellencamp's 2006 spring tour, and the band that opened for him on that tour, Little Big Town, was called on to record harmonies on the studio version of "Our Country", as well as seven other songs on Freedom's Road. Although Mellencamp had always been outspoken and adamant about not selling any of his songs to corporations to use in commercials, he changed his stance and let Chevrolet use "Our Country" in Chevy Silverado TV commercials that began airing in late September 2006.  "I agonized", Mellencamp told USA Today's Edna Gundersen in 2007 over his decision to license "Our Country" to Chevrolet. "I still don't think we should have to do it, but record companies can't spend money to promote records anymore, unless you're U2 or Madonna. I'm taking heat because no one's ever done this before. People have licensed songs that have already been hits, but nobody's licensed a brand-new song to a major company, and people don't know how to react."  Mellencamp sang "Our Country" to open Game 2 of the 2006 World Series, and the song was nominated for a 2008 Grammy Award in the Best Solo Rock Vocal Performance category, but lost to Bruce Springsteen's "Radio Nowhere." Freedom's Road peaked at No. 5 on the Billboard 200 album chart by selling 56,000 copies in its first week on the market.

input: 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.
