Kessler Twins
Their parents, Paul and Elsa, sent them to ballet classes at the age of six, and they joined the Leipzig Opera's child ballet program at age 11. When they were 18, their parents used a visitor's visa to escape from East Germany to West Germany, where they performed at the Palladium in Düsseldorf. They performed at Le Lido in Paris between 1955 and 1960, and represented West Germany in the 1959 Eurovision Song Contest, finishing in 8th place with Heute Abend wollen wir tanzen geh'n (Tonight we want to go dancing).
