Answer the question at the end by quoting:

John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
London was vulnerable to accusations of plagiarism, both because he was such a conspicuous, prolific, and successful writer and because of his methods of working. He wrote in a letter to Elwyn Hoffman, "expression, you see--with me--is far easier than invention." He purchased plots and novels from the young Sinclair Lewis and used incidents from newspaper clippings as writing material.  In July 1901, two pieces of fiction appeared within the same month: London's "Moon-Face", in the San Francisco Argonaut, and Frank Norris' "The Passing of Cock-eye Blacklock", in Century Magazine. Newspapers showed the similarities between the stories, which London said were "quite different in manner of treatment, [but] patently the same in foundation and motive." London explained both writers based their stories on the same newspaper account. A year later, it was discovered that Charles Forrest McLean had published a fictional story also based on the same incident.  Egerton Ryerson Young claimed The Call of the Wild (1903) was taken from Young's book My Dogs in the Northland (1902). London acknowledged using it as a source and claimed to have written a letter to Young thanking him.  In 1906, the New York World published "deadly parallel" columns showing eighteen passages from London's short story "Love of Life" side by side with similar passages from a nonfiction article by Augustus Biddle and J. K Macdonald, titled "Lost in the Land of the Midnight Sun".  London noted the World did not accuse him of "plagiarism", but only of "identity of time and situation", to which he defiantly "pled guilty".  The most serious charge of plagiarism was based on London's "The Bishop's Vision", Chapter 7 of his novel The Iron Heel (1908). The chapter is nearly identical to an ironic essay that Frank Harris published in 1901, titled "The Bishop of London and Public Morality". Harris was incensed and suggested he should receive 1/60th of the royalties from The Iron Heel, the disputed material constituting about that fraction of the whole novel. London insisted he had clipped a reprint of the article, which had appeared in an American newspaper, and believed it to be a genuine speech delivered by the Bishop of London.

Did London ever accuse someone else of plagiarism?



Some context: Winger is an American rock band that has combined elements of glam metal and progressive metal. Formed in New York City, Winger gained popularity during the late 1980s and early 1990s. The band's two platinum albums, Winger and In the Heart of the Young, along with charting singles "Seventeen", "Headed for a Heartbreak" and "Miles Away", put the band on the top of the charts by the early 1990s. In 1990, the band was nominated for an American Music Award for "Best New Heavy Metal Band".
In 2001, it was announced that all original members of the band would return to the studio to record the song "On the Inside" for The Very Best of Winger. In 2002, all five members embarked on a reunion tour of the U.S. and Canada on a bill with Poison. According to Kip Winger, in a 2008 interview with rock and roll comic C.C. Banana, it was important to include all five members because "it was the big, long-awaited reunion so I wanted to include everybody who had ever been in the band." In 2003, it was confirmed that activity had been halted due to Reb Beach's touring commitment with Whitesnake as well as his solo album "Masquerade" and involvement with "supergroup" project The Mob with King's X frontman Doug Pinnick and Night Ranger drummer Kelly Keagy.  On July 16, 2005, it was announced that Kip Winger would perform as the lead singer for the Alan Parsons Live Project at the Common Ground Music Festival in Lansing, Michigan. In May 2006, it was confirmed that Winger had reformed without one of its original members Paul Taylor, to record another album and tour Europe. The album, IV, was released in Europe in October and the nine-country "Winger IV Tour" ran in the last two weeks of the same month.  On February 25, 2008, the band performed in Providence, Rhode Island, as part of a benefit for survivors of the Station nightclub fire. The concert, along with other artists was debuted on VH1 Classic on March 23, 2008. In late 2009, it was confirmed that Winger would record a fifth album Karma, with a tour to support it. Most recently, John Roth became the guitarist for Giant and will appear on their latest album Promise Land set for release in February/March 2010.  Winger released their sixth studio album titled, Better Days Comin' in April 2014, after teasers were published on Kip Winger's website and on the official Winger Facebook page as well.
Did they perform with any other groups?

IN: Kenule Beeson "Ken" Saro-Wiwa (10 October 1941 - 10 November 1995) was a Nigerian writer, television producer, environmental activist, and winner of the Right Livelihood Award and the Goldman Environmental Prize. Saro-Wiwa was a member of the Ogoni people, an ethnic minority in Nigeria whose homeland, Ogoniland, in the Niger Delta has been targeted for crude oil extraction since the 1950s and which has suffered extreme environmental damage from decades of indiscriminate petroleum waste dumping. Initially as spokesperson, and then as president, of the Movement for the Survival of the Ogoni People (MOSOP), Saro-Wiwa led a nonviolent campaign against environmental degradation of the land and waters of Ogoniland by the operations of the multinational petroleum industry, especially the Royal Dutch Shell company. He was also an outspoken critic of the Nigerian government, which he viewed as reluctant to enforce environmental regulations on the foreign petroleum companies operating in the area.

Saro-Wiwa was arrested again and detained by Nigerian authorities in June 1993 but was released after a month. On 21 May 1994 four Ogoni chiefs (all on the conservative side of a schism within MOSOP over strategy) were brutally murdered. Saro-Wiwa had been denied entry to Ogoniland on the day of the murders, but he was arrested and accused of incitement to them. He denied the charges but was imprisoned for over a year before being found guilty and sentenced to death by a specially convened tribunal. The same happened to eight other MOSOP leaders who, along with Saro-Wiwa, became known as the Ogoni Nine.  Some of the defendants' lawyers resigned in protest against the alleged rigging of the trial by the Abacha regime. The resignations left the defendants to their own means against the tribunal, which continued to bring witnesses to testify against Saro-Wiwa and his peers. Many of these supposed witnesses later admitted that they had been bribed by the Nigerian government to support the criminal allegations. At least two witnesses who testified that Saro-Wiwa was involved in the murders of the Ogoni elders later recanted, stating that they had been bribed with money and offers of jobs with Shell to give false testimony, in the presence of Shell's lawyer.  The trial was widely criticised by human rights organisations and, half a year later, Ken Saro-Wiwa received the Right Livelihood Award for his courage, as well as the Goldman Environmental Prize.  On 10 November 1995, Saro-Wiwa and the rest of the Ogoni Nine were killed by hanging by military personnel. They were buried in Port Harcourt Cemetery.  In his 1989 short story "Africa Kills Her Sun", Saro-Wiwa in a resigned, melancholic mood, foreshadowed his own execution.
