July 18 | “No Nukes!,” the movie, premiered on this date in 1980. The concert film, about the three-day benefit held at New York’s Madison Square Garden the year before, featured Bruce Springsteen, Jackson Browne, Crosby Stills & Nash and several others. In 1983, Abbey Road Recording Studios, where almost all the Beatles’ recordings were done, opened its doors to the public for the first time. But just for the seven weeks it took to install a new mixing board. And today in 1978, Def Leppard made their live debut while they were all still teenagers, playing a show at Westfield School in Sheffield, England in front of 150 students.
