David Bowie, a hero who helped to bring down the Berlin Wall, apparently

According to VICE News, the German Foreign Ministry credited Bowie with helping to bring down the Berlin Wall:

"Bowie lived in Berlin from 1976 to 1979 with punk legend Iggy Pop, where he helped produce Iggy's seminal album The Idiot as well as releasing three of his own.
In 1987, two years before the wall was pulled down, he returned to play a concert in West Berlin close to the partition so that East Germans could hear it. In German, he sent best wishes to the thousands of people listening on the other wall before launching into Heroes, a song he wrote there, sparking rioting in East Berlin".
