Answer the question at the end by quoting:

AKB48 (pronounced A.K.B. Forty-eight) are a Japanese idol girl group named after the Akihabara (Akiba for short) area in Tokyo, where the group's theater is located. The group has expanded since then to include over 130 members as of December 2015, aged from their early teens to their mid-20s. AKB48's producer, Yasushi Akimoto, wanted to form a girl group with its own theater (unlike pop groups performing occasional concerts and seen on television) and performing daily so fans could always see them live. This "idols you can meet" concept includes teams which can rotate performances and perform simultaneously at several events and "handshake" events, where fans can meet group members.
In October 2006 AKB48 announced auditions for Team B, and 13 girls were chosen out of 12,828 applicants in December. The group's first DefStar Records single, "Aitakatta", was recorded by 20 members of Teams A and K and released on October 25. It debuted at number 12 on the Oricon weekly singles chart, selling 25,544 copies in its first six weeks, and remained on the chart for a total of 65 weeks. On November 3-4 AKB48 performed its first concert, "AKB48 First Concert: Aitakatta ~Hashira wa Nai ze!~" at Nippon Seinenkan in Shinjuku. The group performed "Aitakatta" on the New Year's Eve TV program 58th NHK Kohaku Uta Gassen as a part of the "Nihon ga Hokoru Saisentan! Special Medley". At 43 members, the group set a program record for the most people in one group onstage simultaneously. AKB48 made its first lineup change in December, transferring Kazumi Urano, Shiho Watanabe and Natsumi Hirajima from Team A to Team B as supporting members.  AKB48's second major-label single, "Seifuku ga Jama o Suru", was released on January 31, 2007 and debuted at number seven on the Oricon Top 10 chart. Its music video and lyrics hinted at the subject of enjo kosai (compensated dating, remotely related to escort services outside Japan), triggering controversy and negative reviews. On March 18 AKB48 released "Keibetsu Shiteita Aijo"; debuting at number eight on the Oricon chart, it dropped to number 98 in its second week. The group's second concert, "AKB48 Haru no Chotto dake Zenkoku Tour ~Madamada daze AKB48!~" on March 10, had poor ticket sales.  In April 2007 AKB48 posted its Team B roster on its website, with five fewer members than originally announced; for the first time, its membership numbered 48. The group's fourth single, "Bingo!", was released on July 18. AKB48's sixth single, "Yuhi o Miteiru ka?", was released on Halloween 2007 and sold 18,429 copies (the least of all the group's singles).

Did Aitakatta make it on the charts?

It debuted at number 12 on the Oricon weekly singles chart, selling 25,544 copies in its first six weeks, and remained on the chart for a total of 65 weeks.

Some context: Armando Anthony "Chick" Corea (born June 12, 1941) is an American jazz pianist/electric keyboardist and composer. His compositions "Spain", "500 Miles High", "La Fiesta" and "Windows", are considered jazz standards. As a member of Miles Davis's band in the late 1960s, he participated in the birth of jazz fusion. In the 1970s he formed the fusion band Return to Forever.
In the 1970s Corea started working with vibraphonist Gary Burton, with whom he recorded several duet albums for ECM, including 1972's Crystal Silence. They reunited in 2006 for a concert tour. A new record called The New Crystal Silence was issued in 2008 and won a Grammy Award in 2009. The package includes a disc of duets and another disc with the Sydney Symphony Orchestra.  Toward the end of the 1970s, Corea embarked on a series of concerts and two albums with Hancock. These concerts were presented in elegant settings with both pianists dressed formally and performing on Yamaha concert grand pianos. The two traded playing each other's compositions, as well as pieces by other composers such as Bela Bartok. In 1982, Corea performed The Meeting, a live duet with the classical pianist Friedrich Gulda.  In December 2007 Corea recorded a duet album, The Enchantment, with banjoist Bela Fleck. Fleck and Corea toured extensively for the album in 2007. Fleck was nominated in the Best Instrumental Composition category at the 49th Grammy Awards for the track "Spectacle".  In 2008 Corea collaborated with Japanese pianist Hiromi Uehara on the live album Duet (Chick Corea and Hiromi). The duo played a concert at Tokyo's Budokan arena on April 30.  In 2015 Corea reprised the duet concert series with Hancock, again sticking to a dueling-piano format, though both also had synthesizers at their station. The first concert in this series was played at the Paramount Theatre in Seattle, and featured improvised music along with iconic songs from each of the duo and standards from other composers.
Did he have duets with anyone else?
A: Toward the end of the 1970s, Corea embarked on a series of concerts and two albums with Hancock.

IN: Henry Hill, Jr. was born on June 11, 1943 in Manhattan, New York, to Henry Hill, Sr., an Irish immigrant and electrician, and Carmela Costa Hill, a Sicilian. The working-class family consisted of Henry and his eight siblings who grew up in Brownsville, a poorer area of the East New York section of Brooklyn. From an early age, Hill admired the local mobsters who socialized across the street from his home, including Paul Vario, a capo in the Lucchese crime family. In 1955, when Hill was 11 years old, he wandered into the cabstand across the street looking for a part-time after-school job.

Hill testified against his former associates to avoid a possible execution by his crew or going to prison for his crimes. His testimony led to 50 convictions.  Jimmy Burke was given 20 years in prison for the 1978-79 Boston College point shaving scandal, involving fixing Boston College basketball games. Burke was also later sentenced to life in prison for the murder of scam artist Richard Eaton. Burke died of lung cancer while serving his life sentence, on April 13, 1996, at the age of 64.  Paul Vario received four years for helping Henry Hill obtain a no-show job to get him paroled from prison. Vario was also later sentenced to ten years in prison for the extortion of air freight companies at JFK Airport. He died of respiratory failure on November 22, 1988, at age 73 while incarcerated in the FCI Federal Prison in Fort Worth.  Hill, his wife Karen, and their two children (Gregg and Gina) entered the U.S. Marshals' Witness Protection Program in 1980, changed their names, and moved to undisclosed locations in Omaha, Nebraska; Independence, Kentucky; Redmond, Washington; and Seattle, Washington. In Seattle, Hill hosted backyard cookouts for his neighbors, and on one occasion, while under the influence of a combination of liquor and drugs, he revealed his true identity to his guests. To the ire of the federal marshals, they were forced to relocate him one final time to Sarasota, Florida. There, a few months had passed, and Hill repeated the same breach of security, causing the government to finally expel him from the Federal Witness Protection Program.

Was he safe while in witness protection?
