[Q]: Question: What year did Vaughn's producer form hiw own label after leaving Mercury? Passage:In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.

[Q]: Question: Of the two people who reached the finals on December 13th who has released the most albums? Passage:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.

[Q]: Question: How old was Roberto Zanetti when "The Rhythm of the Night" was released on his DWA record label? Passage:Corona's first single, "The Rhythm of the Night", was released in Italy in November 1993 on Roberto Zanetti’s DWA record label, and became an instant hit. It featured the voice of Italian singer Giovanna Bersola, better known by her stage name Jenny B. It stayed at number 1 on the Italian music chart for eight consecutive weeks. However, the song was not released elsewhere until the following year. A remixed version of the song became a number 2 hit in the United Kingdom in September 1994. Like several early 1990s Eurodance/Hi-NRG songs that eventually became American hits, such as "Get Ready For This", "Twilight Zone" and "Tribal Dance" by 2 Unlimited and "Strike It Up", "I Don't Know Anybody Else" and "Everybody Everybody" by Black Box, "The Rhythm of The Night" did not become popular in the United States until well after its success had peaked in Europe. However, by spring 1995, the song was all over American radio and clubs, eventually reaching #11 on the Billboard Hot 100. The song was later released as a track in the 1995 debut studio album "The Rhythm of the Night". Lead vocals for the remaining songs in the album were provided by Welsh singer Sandy Chambers who would also provide vocals on the group's second album Walking On Music.
