Louis A. Szekely (born September 12, 1967), better known by his stage name Louis C.K. (), is an American stand-up comedian, writer, actor, and filmmaker. He is known for his use of observational, self-deprecating, dark, and shock humor. In 2012, C.K. won a Peabody Award and has received six Primetime Emmy Awards, as well as numerous awards for The Chris Rock Show, Louie, and his stand-up specials Live at the Beacon Theater (2011) and Oh My God (2013). He has won the Grammy Award for Best Comedy Album twice.
In August 2005, C.K. starred in a half-hour HBO special as part of the stand-up series One Night Stand. Inspired by the work ethic of fellow comedian George Carlin, who had committed to dropping all of his existing material and starting over every year, In June 2006, C.K. starred in and wrote Lucky Louie, a sitcom he created. The series premiered on HBO and was videotaped in front of a studio audience; it was HBO's first series in that format. Lucky Louie is described as a bluntly realistic portrayal of family life. HBO canceled the series after its first season. He appeared in three films in 2008: Welcome Home Roscoe Jenkins, Diminished Capacity, and Role Models. C.K. launched his first hour-long special, Shameless, in 2007, which aired on HBO and was later released on DVD. In March 2008, he recorded a second hour-long special, Chewed Up, which premiered on Showtime Network on October 4, 2008, and was nominated for a Primetime Emmy Award for Outstanding Writing for a Comedy or Variety Special.  C.K. and his wife Alix Bailey divorced in 2008, with C.K. and Bailey sharing joint custody of their children. In a 2010 interview, C.K. talked about how, after his divorce, he thought, "well, there goes my act." He alluded to the way that his marriage had been central to his act and his life, and he said that it took him approximately a year to realize "I'm accumulating stories here that are worth telling." One element in his preparation for stand-up was training at the same boxing gym as Lowell, Massachusetts fighter Micky Ward, trying to "learn how to ... do the grunt work and the boring, constant training so that you'll be fit enough to take the beating."  On April 18, 2009, C.K. recorded a concert film titled Hilarious. Unlike his previous specials--which had all been produced for television networks--Hilarious was produced independently, directed by C.K. himself, and sold to Epix and Comedy Central after it was complete. As a result, it was not released until late 2010. It was published on DVD and CD in 2011. It is the first stand-up comedy film accepted into the Sundance Film Festival. From 2009 to 2012, C.K. played Dave Sanderson, a police officer and ex-boyfriend of Leslie Knope (played by Amy Poehler) in the sitcom Parks and Recreation. He also co-starred in the romantic comedy fantasy film The Invention of Lying, directed by and starring Ricky Gervais, in 2009.

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".
Journey's album sales did not improve and Columbia Records requested that they change their musical style and add a frontman, with whom keyboardist Gregg Rolie could share lead vocal duties. The band hired Robert Fleischman and transitioned to a more popular style, akin to that of Foreigner and Boston. Journey went on tour with Fleischman in 1977 and together the new incarnation of the band wrote the hit "Wheel in the Sky"; however, management differences resulted in Fleischman leaving within the year.  In late 1977, Journey hired Steve Perry as their new lead singer. Herbie Herbert, the band's manager, also hired Roy Thomas Baker as a producer to add a layered sound approach as Baker had done with his previous band, Queen. With their new lead singer and talented new producer, Journey released their fourth album, Infinity (1978). This album set Journey on their road to stardom with their first RIAA-certified platinum album. This album, with their hit song "Wheel in the Sky" (#57 U.S.), set Journey on a new path with a more mainstream sound to make their highest chart success to date.  In late 1978, manager Herbie Herbert fired drummer Aynsley Dunbar, who joined Bay Area rivals Jefferson Starship shortly thereafter. He was replaced by Berklee-trained jazz drummer Steve Smith. Perry, Schon, Rolie, Smith and Valory recorded Evolution (1979), which gave the band their first Billboard Hot 100 Top 20 single, "Lovin', Touchin', Squeezin'" (#16); and Departure (1980), which reached No. 8 on the album charts.  Journey's newfound success brought the band an almost entirely new fan base. During the 1980 Departure world tour, the band recorded a live album, Captured.  Keyboardist Gregg Rolie then left the band, the second time in his career he left a successful act. Keyboardist Stevie "Keys" Roseman was brought in to record the lone studio track for Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent replacement. With Cain's replacement of Rolie's Hammond B-3 organ with his own synthesizers, the band was poised for a new decade in which they would achieve their greatest musical success.

What did Robert do to bring about those changes?
