Question:
3 Doors Down is an American rock band from Escatawpa, Mississippi, that formed in 1996. The band originally consisted of Brad Arnold (lead vocals/drums), Todd Harrell (bass), and Matt Roberts (lead guitar, backing vocals). They were soon joined by rhythm guitarist Chris Henderson. The band rose to international fame with their first single, "Kryptonite", which charted in the top three on the Billboard Hot 100 chart.
3 Doors Down's first studio album, The Better Life, was released on February 8, 2000 and went on to become the 11th best-selling album of the year, selling over three million copies. It has since been certified 6x platinum, thanks in large part to the international hit singles, "Kryptonite", "Loser", and "Duck and Run". A fourth single, "Be Like That" was re-recorded for the 2001 film American Pie 2, with alternate lyrics for the first 3 lines. This version is known as "The American Pie 2 Edit". Whilst recording the album, Brad Arnold recorded both the vocal and drum parts. However, the band hired drummer Richard Liles for the tour in support of The Better Life so that Arnold could perform at the front of the stage. Liles left in late 2001. The band's second studio album, Away from the Sun, was released on November 12, 2002 and went platinum within two months of release. The album also produced two hit singles, "When I'm Gone" and "Here Without You". The album has sold four million copies worldwide, including well over three million in the U.S. Session drummer Josh Freese was hired to record drums for the album. Rush guitarist Alex Lifeson produced and performed on three tracks for the record, "Dangerous Game", "Dead Love", and "Wasted Me", but only "Dangerous Game" would appear on the finished product. The band hired Canadian Daniel Adair to play drums for the Away From the Sun tour. He would go on to record the drums for the band's next studio release, and was with the band aboard the USS George Washington (CVN-73) to film the music video "When I'm Gone". In 2003, 3 Doors Down released a live EP entitled Another 700 Miles consisting of recordings from a live performance by the band in Chicago, Illinois. Another 700 Miles has since been certified Gold in the United States. In addition to featuring some of 3 Doors Down's hit singles from their previous two albums, the EP also contains a version of the popular 1977 Lynyrd Skynyrd song "That Smell". The group toured with Nickelback in 2004. In 2003, the band began hosting the annual "3 Doors Down and Friends" benefit concert, through the band's own charity The Better Life Foundation. In 2006, this event was held at the Mobile Convention Center, with proceeds benefiting Hurricane Katrina survivors. As residents of Escatawpa, the members of the band saw the effects of Katrina's devastation.

Question:
Gregory James "Greg" LeMond (born June 26, 1961) is an American former professional road racing cyclist who won the Road Race World Championship twice (1983 and 1989) and the Tour de France three times (1986, 1989 and 1990). He is also an entrepreneur and anti-doping advocate. LeMond was born in Lakewood, California, and raised in ranch country on the eastern slopes of the Sierra Nevada mountain range, near Reno. He is married and has three children with his wife Kathy, with whom he supports a variety of charitable causes and organizations.
LeMond is a longtime vocal opponent of performance-enhancing drug use. He first spoke on-record against doping in cycling after winning the 1989 Tour de France. LeMond received intense criticism in 2001 when he publicly expressed doubts about the legitimacy of Lance Armstrong's Tour success after learning of his relationship with Dr. Michele Ferrari. His outspokenness placed him in the center of the anti-doping controversy. LeMond has consistently questioned the relationship between riders and unethical sports doctors like Ferrari, and has pointed out that doping products ultimately victimize the professional cyclists who make use of them. Said LeMond: "When I speak out about doping people could translate it and think it was about the riders. Actually I feel like I am an advocate for the riders. I look at them as being treated like lab rats that are test vehicles for the doctors. The doctors, the management, the officials, they're the ones that have corrupted riders. The riders are the only ones that pay the price." LeMond's most notable conflicts have been with fellow Tour riders Lance Armstrong and Floyd Landis. He has also been critical of Alberto Contador, the UCI, and its former president, Pat McQuaid. In December 2012, LeMond claimed that a change needed to be made at the head of leadership for the UCI, and stated if called upon he would be willing to take the position himself if necessary to lead cycling out of the mire of doping. Said LeMond: "It is now or never to act. After the earthquake caused by the Armstrong case another chance will not arise. I am willing to invest to make this institution more democratic, transparent and look for the best candidate in the longer term." McQuaid rejected LeMond's call for new leadership and was dismissive of LeMond. Ultimately McQuaid was defeated in his bid for a third term by British Cycling president Brian Cookson at the September 2013 UCI Congress in Florence, Italy. Lemond had supported Cookson in the UCI Presidential battle.
