Answer the question at the end by quoting:

Dion Francis DiMucci (born July 18, 1939), better known mononymously as Dion, is an American singer, songwriter whose work has incorporated elements of doo-wop, rock and R&B styles--and, most recently, straight blues. He was one of the most popular American rock and roll performers of the pre-British Invasion era. He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, with the Belmonts or with the Del Satins. He is best remembered for the singles "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among his other hits.
Bob and Gene Schwartz also signed Dion's friends, the Belmonts, (Carlo Mastrangelo, Fred Milano, and Angelo D'Aleo), a vocal group named for nearby Belmont Avenue, and teamed them, with Dion singing lead. The new group's breakthrough came in early 1958, when "I Wonder Why" (on their newly formed "Laurie" label) made No. 22 on the U.S. charts. Dion said of the Belmonts; "I'd give 'em sounds. I'd give 'em parts and stuff. That's what 'I Wonder Why' was about. We kind of invented this percussive rhythmic sound. If you listen to that song, everybody was doing something different. There's four guys, one guy was doing bass, I was singing lead, one guy's going 'ooh wah ooh,' and another guy's doing tenor. It was totally amazing. When I listen to it today, oftentimes I think, 'man, those kids are talented.'" Their initial hit was followed by "No One Knows" and "Don't Pity Me," which also charted the Billboard Top 100. This success won a place for Dion and the Belmonts on the ill-fated "The Winter Dance Party" tour with Buddy Holly, Ritchie Valens, the Big Bopper (J.P. Richardson), Frankie Sardo, and other performers. On February 3, 1959, after a concert stop in Clear Lake, Iowa, Holly and others decided to charter a flight to the next venue rather than travel on the tour bus. Dion was invited to accompany the group but decided that he did not want to spend $36 for the flight, as it was the same monthly rent his parents paid for his childhood apartment and he couldn't justify the indulgence. The plane crashed, killing all on board; Holly, Valens, Richardson, and the pilot Roger Peterson. Dion and the Belmonts continued on the tour, along with Frankie Sardo, while Bobby Vee, then an unknown artist, performed in Holly's place at the very next concert. Later, Jimmy Clanton, Frankie Avalon, and Fabian were added to replace the other now-deceased headliners. Dion and the Belmonts' next single, "A Teenager in Love," was released in March 1959, eventually hitting No. 5 on the U.S. pop charts and No. 28 in the UK. The group's biggest hit, "Where or When," was released in November of that year, and reached No. 3 on the U.S. charts. However, in early 1960, Dion checked into hospital for heroin addiction, a problem he had had since his mid-teens. Further single releases for the group that year were less successful. There were musical, personal and financial differences between Dion and members of the Belmonts, and in October 1960, Dion decided to quit for a solo career. By the time of their breakup, all eight Laurie releases had charted on the Hot 100.

when did the group split up?

in October 1960, Dion decided to quit for a solo career.

IN: 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.
