Nothing like a little Julie Andrews to brighten your day. A friend sent me this YouTube link. The video was made in the Antwerp , Belgium Central (Train) Station on March 23, 2009.
". . . with no warning to the passengers passing through the station, at 8:00 a.m., a recording of Julie Andrews singing 'Do, Re, Mi' began to play on the public address system. As the bemused passengers watch in amazement, some 200 dancers began to appear from the crowd and station entrances. They created this amazing stunt with just two rehearsals." Enjoy!
