Question: The Chaser is an Australian satirical comedy group. They are known for their television programmes on the Australian Broadcasting Corporation channel. The group take their name from their production of satirical newspaper, a publication known to challenge conventions of taste. The group's motto is "Striving for Mediocrity in a World of Excellence".

In July 2006, Licciardello faced charges of "offensive conduct" from the New South Wales Police Force, after turning up at a rugby league football match between the Canterbury Bulldogs and the St George Illawarra Dragons on 14 July 2006 dressed up as a Bulldogs fan and attempting to sell fake knives, knuckledusters and balaclavas for a War on Everything sketch. In April 2007, a 15-year-old boy duped YouTube into deleting all clips posted from The Chaser's War On Everything by claiming to be a representative of the ABC. They were later reinstated. At the 2007 Logie Awards some of the Chaser team were "manhandled" by Crown Casino security staff on the red carpet before being closely supervised for the rest of the evening. During Dick Cheney's visit to Australia in 2007, members of The Chaser team were included on the official list of terrorists, anarchists, and protesters deemed to pose a threat to the US Vice-President. The Chaser team gained notoriety and considerable media attention over "The Eulogy Song", written by Chris Taylor and performed by Andrew Hansen on 17 October 2007 episode of The Chaser's War On Everything. The song satirised the media's posthumous praise of deceased celebrities, regardless of their behaviour in life, and mentioned among others John Lennon, Peter Brock, Stan Zemanek, Princess Diana, Steve Irwin, Donald Bradman, and Kerry Packer. The song attracted comment from both the media and politicians including Kevin Rudd and John Howard, the latter of whom used reference to the song in remarks during a sketch later aired on the programme.

Using a quote from the above article, answer the following question: which celebrities did the song reference?

Answer: among others John Lennon, Peter Brock, Stan Zemanek, Princess Diana, Steve Irwin, Donald Bradman, and Kerry Packer.

Problem: William Bartram (April 20, 1739 - July 22, 1823) was an American naturalist. The son of Ann (nee Mendenhall) and the naturalist John Bartram, William Bartram and his twin sister Elizabeth were born in Kingsessing, Philadelphia, Pennsylvania. As a boy, he accompanied his father on many of his travels to the Catskill Mountains, the New Jersey Pine Barrens, New England, and Florida. From his mid-teens, Bartram was noted for the quality of his botanic and ornithological drawings.

Bartram returned to Philadelphia in January 1777 and assisted his brother John in all aspects of running Bartram's Garden. In the late 1780s, he completed the book for which he became most famous, Travels through North and South Carolina, Georgia, East and West Florida, the Cherokee Country, etc.. It was considered at the time one of the foremost books on American natural history. Many of Bartram's accounts of historical sites were the earliest records, including the Georgia mound site of Ocmulgee. In addition to its contributions to scientific knowledge, Travels is noted for its original descriptions of the American countryside. Bartram's writing influenced many of the Romantic writers of the day. William Wordsworth, Samuel Taylor Coleridge, and Francois-Rene de Chateaubriand are known to have read the book, and its influence can be seen in many of their works. Although Bartram has often been characterized as a recluse, all evidence shows that he remained active in commercial, scientific, and intellectual pursuits well into the nineteenth century. He tutored nieces and nephews, penned a number of essays, contributed to several works anonymously, and helped run the family horticultural business. In 1802, Bartram met the school teacher Alexander Wilson and began to teach him the rudiments of ornithology and natural history illustration. Wilson's American Ornithology includes many references to Bartram and the area around Bartram's Garden. Among Bartram's more significant later contributions were the illustrations for his friend Benjamin Smith Barton's explanation of the Linnaean system, Elements of Botany (1803-04). After the War of 1812, when many of his colleagues, contacts, and friends had died, Bartram settled into a long period of work, observation, and study at the family's garden in Kingsessing. He maintained a "Diary" that records bird migrations, plant life, and the weather. He refused a request to teach botany at the University of Pennsylvania, and in his sixties, declined an invitation from President Thomas Jefferson to accompany an expedition up the Red River in the Louisiana Territory, in 1806. He died at his home at the age of 84.
