Question: When did the conductor at Midori's concert debut begin conducting the New York Philharmonic? Passage 1:"Enjoy Yourself" is a song recorded by The Jacksons and released as a single in 1976. Featuring Michael and Jackie Jackson on lead vocals, it was the first non-Motown single for the group since they departed from the label earlier that year. The song peaked at #6 on the Billboard Hot 100 chart on February 19, 1977. On other US charts, "Enjoy Yourself" peaked at #2 on the Hot Soul Singles chart, and #33 on the National Disco Action Top 40 chart. On February 14, 1989, it became the group's first single to be certified Platinum by the RIAA. It was also the group's first song to feature new member Randy Jackson, who replaced Jermaine when he decided to stay at Motown after his brothers left. The song is sampled on the track "Let's Have a Party" by the Backstreet Boys, which appears on their 1996 self-titled debut album. The song is credited to Philadelphia songwriters/producers Gamble and Huff; however, a session musician from Gamble and Huff’s in-house band recalled that the late guitarist T.J. Tindall wrote the riff that was the initial spark for the song.
 Passage 2:For 1970, Matra insisted on using their own V12 engines, while Tyrrell and Stewart wanted to continue with the Cosworth and maintain their connection to Ford, which conflicted with Matra's recent connections to Chrysler. Tyrrell decided to build his own car and in the interim bought a chassis from March Engineering; Stewart took the March 701-Cosworth to wins at the Daily Mail Race of Champions and Jarama, but development on the car stalled and it was soon overcome by the Lotus team's new 72. The new Tyrrell 001-Cosworth, appeared in August and suffered problems but showed promise. Tyrrell continued to be sponsored by French fuel company Elf, and Stewart raced in a car painted French Racing Blue for many years. Stewart also continued to race sporadically in Formula Two, winning at Crystal Palace and placing at Thruxton. A projected Le Mans appearance, to co-drive the 4.5 litre Porsche 917K with Steve McQueen, did not come off, due to McQueen's inability to get insurance. He also had a one-off race in Can-Am, in the revolutionary Chaparral 2J. Stewart qualified third, in what was the car's first outing, but brake failure ended his race.
 Passage 3:Midori gave her first public performance at the age of six, playing one of the 24 Caprices of Paganini in her native Osaka. In 1982 she and her mother moved to New York City, where Midori started violin studies with Dorothy DeLay at Pre-College Division of Juilliard School and the Aspen Music Festival and School. As her audition piece, Midori performed Bach's thirteen-minute-long Chaconne, generally considered one of the most difficult solo violin pieces. In the same year, she made her concert debut with the New York Philharmonic under Zubin Mehta, a conductor with whom she would later record on the Sony Classical label. In 1986 came her legendary performance of Leonard Bernstein's Serenade at Tanglewood, conducted by Bernstein. During the performance, she broke the E string on her violin, then again on the concertmaster's Stradivarius after she borrowed it. She finished the performance with the associate concertmaster's Guadagnini and received a standing ovation. The next day The New York Times front page carried the headline, "Girl, 14, Conquers Tanglewood with 3 Violins".
