IN: Daniel Milton Rooney (July 20, 1932 - April 13, 2017) was chairman of the Pittsburgh Steelers, an American football team in the National Football League (NFL), and son of the Steelers' founder, Art Rooney. Dan Rooney was elected to the Pro Football Hall of Fame in 2000 for his contributions to the game. He was credited with spearheading a requirement that NFL teams with head coach and general manager vacancies interview at least one minority candidate, which has become known as the "Rooney Rule". Rooney served as the United States Ambassador to Ireland, from July 2009 until his resignation in December 2012.

On March 17, 2009, President Obama announced he had nominated Rooney to become the next US ambassador to Ireland, citing the owner's longstanding support for Irish-American charitable causes. In 2008, Rooney gave $30,000 to a Democratic Party committee that aided Obama's campaign, according to CQ MoneyLine, a non-partisan group that tracks political contributions. According to David Lewis, a Vanderbilt University political scientist and the author of The Politics of Presidential Appointments, "giving coveted ambassadorships to political supporters is a relatively low-risk way for presidents to repay campaign debts." Secretary of State Hillary Clinton swore him in as the new ambassador to Ireland on July 1, 2009. Ambassador Rooney presented his credentials to Irish President Mary McAleese on July 3, before making his first official speaking engagement at lunch hosted by the American Chamber of Commerce Ireland. In an interview with The Irish Times in April 2011 Rooney mentioned that he would consider resigning his ambassadorship in order to campaign for Obama's re-election. However, in a prepared statement released after that interview was published Rooney stated, "I was asked what I could do to help [Obama] in the next election and I responded that the best thing I could do would be to help him campaign. Were I to do so, it would require my resignation as ambassador to Ireland. However, I am very pleased with my accomplishments to date and I intend to continue to carry out my duties." On December 14, 2012, he resigned as US Ambassador to Ireland and returned to Pittsburgh. He would eventually be replaced in June 2014 by Kevin O'Malley. Rooney was the maternal great-uncle of actresses Kate Mara and her sister Rooney Mara.

IN: Kanjani Eight (Guan ziyani[?](eito), Kanjani Eito, stylized as Kanjani[?]) is a seven-member Japanese boy band from Japan's Kansai region. They are managed by the multimedia talent agency, Johnny & Associates, and signed to Imperial Records. The group was formed in 2002 and made their CD debut in 2004 as "Johnny's modern enka group", though after the year 2006, their sound and style has become a mix of pop and rock. Like the rest of the acts managed under Johnny & Associates, Kanjani Eight also perform in various other areas of the Japanese entertainment industry such as variety show hosting, television, movie, and stage acting, and radio talk show hosting.

Although Nishikido and Uchi were already members of NEWS, they went on to also debut as members of Kanjani Eight when the group released their debut single titled "Naniwa Iroha Bushi" in the Kansai area on August 25, 2004. The single became a local hit, capturing the traditional feel of their hometown region through the pop-enka tune. Shibutani had said, in regards to the feel of the song, " The song has a Kawachi Workman's bass, so it's entirely something new. It'd make me happy to see others dancing when they hear it." Despite the release of the CD, their debut was lackluster, leaving many to question if the debut actually was real. The members themselves had found out of the debut through a newspaper article; Shibutani had said that he was "very surprised" when he found out. Even though there was questions about the group's debut, "Naniwa Iroha Bushi" had risen to the number-one spot on the Oricon's Enka charts and reaching number-eight on the Oricon's generic music charts. When the single made its nationwide debut on September 22, it had hit number-one on both the Oricon Enka and General Music charts. Much of 2004 activities were Kansai region focused in comparison their fellow acts who had the luxuries of nationwide exposure. Kanjani Eight had become hometown idols with majority of their popularity within the region but outside the area they were almost unknown. The release of their second single, "Osaka Rainy Blues", further exemplified the fact with the CD single debuting number-nine on the Oricon. To this date, "Osaka Rainy Blues" is the group's lowest single in sales. 2005 had marked the launch of Kanjani Eight's popularity even though it had opened up with the lackluster sales of their second single, "Osaka Rainy Blues". The group had been starring in three regular programs, now being aired nationwide, and were starting to get recognition as a debut Johnny's act. But with growing success came a scandal and in 2005 Hiroki Uchi was arrested for disorderly conduct and underage drinking, being 18 at the time. The scandal had a significant impact on Kanjani Eight as well as NEWS, the other group he was active in. Johnny's & Associates removed Uchi from both units and put him under an indefinite hiatus from all activities. Also, the drama special about the World War II Kamikaze pilots starring the group, Yakusoku, was canceled. Kanjani Eight continued on that year to do their first Osaka-jo Hall performance with one member less in the summer of 2005.
