Who was the wife of  Jean Michel Jarre's friend who died during the Challenger launch?
Rendez-vous Houston Rendez-vous Houston: A City in Concert was a live performance by musician Jean Michel Jarre amidst the skyscrapers of downtown Houston on the evening of April 5, 1986, coinciding with the release of the "Rendez-Vous" album. For a period of time, it held a place in the "Guinness Book of Records" as the largest outdoor "rock concert" in history, with figures varying from 1 to 1.5 million in attendance. Rendez-vous Houston is remembered for being the concert which celebrated the astronauts of the Space Shuttle "Challenger" disaster, which had happened only two and a half months earlier. One of Jarre's friends, astronaut Ron McNair, had been killed in the disaster. He was supposed to play the saxophone from space during the track "Last Rendez-Vous"; his substitute for the concert was Houston native Kirk Whalum.
