Background: Irwin was born on his mother's birthday to Lyn and Bob Irwin in Essendon, a suburb of Melbourne, Victoria. He was of Irish descent on his father's side. He moved with his parents as a child to Queensland in 1970, where he attended Landsborough State School and Caloundra State High School. Irwin described his father as a wildlife expert interested in herpetology, while his mother Lyn was a wildlife rehabilitator.
Context: News of Irwin's death prompted reactions around the world. Then-Prime Minister John Howard expressed "shock and distress" at the death, saying that "Australia has lost a wonderful and colourful son." Queensland's then-Premier Peter Beattie remarked that Irwin would "be remembered as not just a great Queenslander, but a great Australian". The Australian federal parliament opened on 5 September 2006 with condolence speeches by both Howard and the Leader of the Opposition, Kim Beazley. Flags at the Sydney Harbour Bridge were lowered to half mast in honour of Irwin. In the days following Irwin's death, reactions dominated Australian online news sources, talk-back radio programmes, and television networks. In the United States, where Irwin had appeared in over 200 Discovery Network television programmes, special tributes appeared on the Animal Planet channel, as well as on CNN and major TV talk shows. Thousands of Irwin's fans visited Australia Zoo after his death, paying their respects and bringing flowers, candles, stuffed animals and messages of support. Criticism of Irwin's career following his death came from Dan Mathews, vice-president of the animal rights group People for the Ethical Treatment of Animals. Comparing Irwin to a "cheap reality TV star", Mathews accused him of "antagonising frightened wild animals ... a very dangerous message to send to children", contrasted his methods with the behaviour of "a responsible conservationist like Jacques Cousteau", and said it was "no shock at all that Steve Irwin should die provoking a dangerous animal." The son of Jacques Cousteau, Jean-Michel Cousteau--also a producer of wildlife documentaries--took issue with Irwin's "very, very spectacular, dramatic way of presenting things" and suggested instead that "You don't touch nature, you just look at it." Jacques Cousteau's grandson and Jean-Michel's nephew, Philippe Cousteau Jr., on the other hand, called Irwin "a remarkable individual"; describing the Ocean's Deadliest project (on which he worked along with Irwin), Philippe said, "I think why Steve was so excited about it that we were looking at these animals that people think of as, you know, dangerous and deadly monsters, and they're not. They all have an important place in the environment and in the world. And that was what his whole message was about." In the weeks following Irwin's death, at least ten stingrays were found dead and mutilated on the beaches of Queensland, with their tails cut off, prompting speculation as to whether they might have been killed by fans of Irwin as an act of revenge, although, according to the chairman of the Queensland fishing information service, anglers regularly cut the tails off of accidentally caught stingrays to avoid being stung. Michael Hornby, a friend of Irwin and executive director of his Wildlife Warrior fund, condemned any revenge killings, saying that "We just want to make it very clear that we will not accept and not stand for anyone who's taken a form of retribution. That's the last thing Steve would want."
Question: Did John Howard participate in any memorial services?
Answer:

Background: 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.
Context: 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.
Question: How long did the tour last?
Answer:
On the second leg of the tour in the summer of 2005, Fogerty co-headlined with Mellencamp at outdoor amphitheaters across the United States.
