After Dieter Braun won the East German Grand Prix in 1971 the West German national anthem was played during the winner's ceremony. The East German crowd began singing the words to the anthem. The Soviet controlled DDR government reacted by making the following year's East German Grand Prix an invitation only race, and in 1973, the race was removed from the GP calendar.
