Background: The son of well-known surfer Jeff Johnson, Jack was born and raised on the North Shore of Oahu, Hawaii. He began to learn how to surf at the age of five. At seventeen he became the youngest invitee to make the finals of the Pipeline Masters, one of surfing's most prestigious surfing events, on Oahu's North Shore. One week later, however, his stint as a professional surfer ended when he suffered a surfing accident at the Pipeline that put more than 150 stitches in his forehead and removed a few of his teeth; this later became the inspiration for the song "Drink the Water".
Context: In 2008, Johnson and his wife Kim created the Johnson Ohana Charitable Foundation, a non-profit public charity supporting environmental, art, and music education worldwide. Jack and Kim Johnson also founded the Kokua Hawaii Foundation in 2003. Johnson and his family work hard every year at festivals and concerts alike, to raise money for causes they feel are most important. Johnson recorded a cover of John Lennon's "Imagine" for the 2007 benefit album Instant Karma: The Amnesty International Campaign to Save Darfur, which was also included on the 2009 benefit album Rhythms del Mundo Classics. In talking about Johnson and his career choices, Rolling Stone wrote: "It is a typically generous move from Johnson, who has used his multi-platinum success to support causes he cares about." Although the Johnson Ohana Charitable Foundation is a non-profit organization that "focuses on environmental, arts and music education", it has raised more than $750,000 from 2009 to 2010 to give away. Johnson was in Osaka, Japan on his To the Sea 2010 World Tour at the time of the 2011 Tohoku earthquake and tsunami in northern Japan. He was in a hotel with his family when it struck. After having to postpone the rest of his tour, he donated $50,000 to GlobalGiving's Japan Earthquake and Tsunami Relief Fund.  Johnson's Ohana Charitable Foundation has also supported Little Kids Rock, a national nonprofit that works to restore and revitalize music education in disadvantaged U.S. public schools. He also decorated a guitar for Little Kids Rock to auction to raise funds for its program.  On September 22, 2012, he donated his time to play a few songs at Farm Aid 2012 in Hershey, PA. Later in 2012, Jack donated $50,000 for Hurricane Sandy relief and added links on his website for others to donate:

Background: Bourke's father, Frank, was serving in the RAAF and on leave in Melbourne when he played a solitary game for Richmond in 1943. A tall (193 cm) and lean (85 kg) full forward with an excellent reputation in country football, Frank returned to the city after the war and resume his playing career with Richmond. In the opening weeks of the 1946 season Frank kicked five or more goals six times in the first seven matches to lead the VFL goalkicking table. Injury curtailed further progress.
Context: Just months after his playing retirement, Bourke was controversially pitched into the coaching position at Punt Road. The Tigers had decided to sack Tony Jewell, a premiership teammate of Bourke, just twelve months after he coached Richmond to the 1980 premiership. Although few doubted that Bourke was coaching material, the nature of his appointment and his lack of coaching experience at any level were significant hurdles to overcome. However, in 1982 Bourke took the Tigers to only their third minor premiership since the war and impressed critics with a brilliant tactical display in the semi final against Carlton. Bourke made a series of positional changes at the beginning of the game and ordered his men to slow down the Carlton play-on game, giving away fifteen-metre penalties as necessary. The Tigers won easily, and Bourke became one of only a handful of coaches to make the Grand Final in his first season.  The dream debut of a premiership was not to be. In the 1982 VFL Grand Final, Richmond led by 11 points at half time, only for Carlton to kick five unanswered goals in the third quarter and run away with the premiership by 18 points.  During the off-season, the Tigers suffered an exodus of disgruntled star players that rocked the club and lost nine of the first eleven games in 1983. Media speculation about the security of Bourke's position began in earnest, and few believed the club when Richmond denied that there was an ongoing crisis. Although the team improved in the second half of the season, further player departures were mooted if Bourke remained as coach. It seemed that his hard-training style was not appreciated by all of his charges. Reluctantly, Bourke tendered his resignation at the end of the season, well aware that he would probably have been sacked had he not done so. His winning rate over the two seasons was a very reasonable 56.5%

Background: David Michael Letterman (born April 12, 1947) is an American television host, comedian, writer, and producer. He hosted a late night television talk show for 33 years, beginning with the February 1, 1982, debut of Late Night with David Letterman on NBC, and ending with the May 20, 2015, broadcast of Late Show with David Letterman on CBS. In total, Letterman hosted 6,028 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late night talk show host in American television history. In 1996 Letterman was ranked 45th on TV Guide's 50 Greatest TV Stars of All Time.
Context: NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray. Murray later went on to become one of Letterman's most recurrent guests, guesting on the show's 30th anniversary episode, which aired January 31, 2012 and on the very last show, which aired May 20, 2015. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher (who even called him an asshole on the show), Shirley MacLaine, Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen.  The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks" (which had its origins on Letterman's morning show), Stupid Human Tricks, dropping various objects off the roof of a five-story building, demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer, Velcro and suet), a recurring Top 10 list, the Monkey-Cam (and the Audience Cam), a facetious letter-answering segment, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog (often with comic results) and Small Town News, all of which would eventually move with Letterman to CBS.  Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC News president and that he was not wearing any pants; walking across the hall to Studio 6B, at the time the news studio for WNBC-TV, and interrupting Al Roker's weather segments during Live at Five; and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared with professional wrestler Jerry Lawler, who slapped and knocked the comedian to the ground (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged).
