One night in 1960, German art student Klaus Voormann went out slumming and came home a changed man. He'd just had an argument with his girlfriend Astrid Kirchherr, and set off to walk the Reeperbahn, a boulevard in the St. Pauli red-light district of Hamburg, Germany. He heard some raucous music pouring from the seedy Kaiserkeller Club, walked inside, and discovered a band of five amphetamine-charged, leather-clad English boys shakin’ down the house. This was his first exposure to a rock-n-roll circus, and he was left – in his words – “speechless.” You could reckon that Mr. Voormann, who turns 77 today, had the distinction of being the first international Beatles fan -- and a whole lot more.
