Kirchherr, Voormann and Vollmer were friends who had all attended the Meisterschule, and shared the same ideas about fashion, culture and music. Voormann became Astrid's boyfriend, and moved into the Kirchherr home, where he had his own room. In 1960, after Kirchherr and Vollmer had had an argument with Voormann, he wandered down the Reeperbahn (in the St. Pauli district of Hamburg) and heard music coming from the Kaiserkeller club. Voormann walked in and watched a performance by a group called the Beatles: Lennon, McCartney, Harrison, Sutcliffe and Best, their drummer at the time. Voormann asked Kirchherr and Vollmer to listen to this new music, and after being persuaded to visit the Kaiserkeller (which was in the rough area of the Reeperbahn), Kirchherr decided that all she wanted to do was to be as close to the Beatles as she could. The trio of friends had never heard rock n' roll before, having previously listened to only trad jazz, with some Nat King Cole and The Platters mixed in. The trio then visited the Kaiserkeller almost every night, arriving at 9 o'clock and sitting by the front of the stage. Kirchherr later said: "It was like a merry-go-round in my head, they looked absolutely astonishing... My whole life changed in a couple of minutes. All I wanted was to be with them and to know them."
