“Youths are prepared to go to any lengths to experience this concert around the area of the Brandenburg Gate [next to the wall],” the Stasi report said, adding that the aim of the clash was to “test the limits of the security organ”.

But they also helped document the fact that he liked girls too, sort of.

“The day before the concert it monitored his visit to the Allied Checkpoint Charlie, at the heart of the then divided city. On a report card next to his name and date of birth, it detailed how he got out of a limousine at 2.52 pm, and was accompanied “at all times by a 25-year-old female.”

“Live life off the wall.”
