Problem: Background: Journey is an American rock band that formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape, the band's eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms".
Context: With Cain on board, the band began writing material that would eventually lead up to Journey's biggest studio album, "Escape". Recording sessions began in April 1981, and lasted until the middle of June. Escape was released on July 31, 1981, and immediately the album became a mainstream success. The album, which has thus far sold nine times platinum, went to number one on the album charts later that year, and included three top-ten hits: "Who's Cryin' Now", "Don't Stop Believin'" and "Open Arms". The last is Journey's highest-charting single to date, staying at No. 2 for six consecutive weeks and ranking at No.34 on Billboard's 1982 year-end Hot 100. MTV videotaped one of their two sold-out shows in Houston on November 6, 1981, in front of over 20,000 fans.  Capitalizing on their success, the band recorded radio commercials for Budweiser and sold rights to their likenesses and music for use in two video games: the Journey arcade game by Bally/Midway and Journey Escape by Data Age for the Atari 2600.  This success was met with criticism. The 1983 Rolling Stone Record Guide gave each of the band's albums only one star, with Dave Marsh writing that "Journey was a dead end for San Francisco area rock." Marsh later would anoint Escape as one of the worst number-one albums of all time.  Journey's next album, Frontiers (1983), continued their commercial success, reaching No. 2 on the album charts, selling nearly six million copies. The album generated four Top 40 hits, "Separate Ways (Worlds Apart)", which reached No. 8, "Faithfully", which reached No. 12, "Send Her My Love" and "After the Fall", both of which reached No. 23. By this time, Journey had become one of the top touring and recording bands in the world. During the subsequent stadium tour, the band contracted with NFL Films to record a video documentary of their life on the road, Frontiers and Beyond. Scenes from the documentary were shot at JFK Stadium in Philadelphia, Pennsylvania with more than 80,000 fans in attendance.

Problem: Background: Abner Doubleday (June 26, 1819 - January 26, 1893) was a career United States Army officer and Union general in the American Civil War. He fired the first shot in defense of Fort Sumter, the opening battle of the war, and had a pivotal role in the early fighting at the Battle of Gettysburg. Gettysburg was his finest hour, but his relief by Maj. Gen. George G. Meade caused lasting enmity between the two men.
Context: Although Doubleday achieved minor fame as a competent combat general with experience in many important Civil War battles, he is more widely known as the supposed inventor of the game of baseball, in Elihu Phinney's cow pasture in Cooperstown, New York, in 1839.  The Mills Commission, chaired by Abraham G. Mills, the fourth president of the National League, was appointed in 1905 to determine the origin of baseball. The committee's final report, on December 30, 1907, stated, in part, that "the first scheme for playing baseball, according to the best evidence obtainable to date, was devised by Abner Doubleday at Cooperstown, New York, in 1839." It concluded by saying, "in the years to come, in the view of the hundreds of thousands of people who are devoted to baseball, and the millions who will be, Abner Doubleday's fame will rest evenly, if not quite as much, upon the fact that he was its inventor ... as upon his brilliant and distinguished career as an officer in the Federal Army."  However, there is considerable evidence to dispute this claim. Baseball historian George B. Kirsch has described the results of the Mills Commission as a "myth". He wrote, "Robert Henderson, Harold Seymour, and other scholars have since debunked the Doubleday-Cooperstown myth, which nonetheless remains powerful in the American imagination because of the efforts of Major League Baseball and the Hall of Fame in Cooperstown." At his death, Doubleday left many letters and papers, none of which describe baseball or give any suggestion that he considered himself a prominent person in the evolution of the game, and his New York Times obituary did not mention the game at all. Chairman Mills himself, who had been a Civil War colleague of Doubleday and a member of the honor guard for Doubleday's body as it lay in state in New York City, never recalled hearing Doubleday describe his role as the inventor. Doubleday was a cadet at West Point in the year of the alleged invention and his family had moved away from Cooperstown the prior year. Furthermore, the primary testimony to the commission that connected baseball to Doubleday was that of Abner Graves, whose credibility is questionable; a few years later, he shot his wife to death and was committed to an institution for the criminally insane for the rest of his life. Part of the confusion could stem from there being another man by the same name in Cooperstown in 1839.  Despite the lack of solid evidence linking Doubleday to the origins of baseball, Cooperstown, New York became the new home of what is today the National Baseball Hall of Fame and Museum in 1937.  There may have been some relationship to baseball as a national sport and Abner Doubleday. While the modern rules of baseball were formulated in New York during the 1840s, it was the scattering of New Yorkers exposed to these rules throughout the country, that spread not only baseball, but also the "New York Rules", thereby harmonizing the rules, and being a catalyst for its growth. Doubleday was a high-ranking officer, whose duties included seeing to provisions for the US Army fighting throughout the south and border states. For the morale of the men, he is said to have provisioned balls and bats for the men.
