In the context of the opera project with the Lappetites (www.lappetites.com) called Fathers, I went with my father Hans-Juergen Greie to the Wall museum in Berlin in 2009 and interviewed him and ask him if he remembers the day when the wall was built when he was 12 years old.

The 13th of August 1961 I spent in Erfurth, a sunday and there was a meeting, a festival of the Pioneers (http://de.wikipedia.org/wiki/Pionierorganisation_Ernst_Th%C3%A4lmann) in connection with a sportive festival and since I played Hockey, I participated in the March (a star- shaped march) to the city of Erfurth and they gave us banner, posters we were supposed to carry up and they said: thanks to the government of the GDR, the Berlin wasp nest is closed for good ! We had no idea what that meant, (these events were filmed and reported with national and i suppose international TV) I was 12, a week later when I came home I found out they had built the wall.
