I just found this, and you may have seen it, but it's new to me and I had to share. I get the most incredible feeling inside when I watch this. I think it is AMAZING!
Here is the info: More than 200 dancers were performing their version of "Do Re Mi", in the Central Station of Antwerp. with just 2 rehearsals they created this amazing stunt! Those 4 fantastic minutes started the 23 of march 2009, 08:00 AM. It is a promotion stunt for a Belgian television program, where they are looking for someone to play the leading role, in the musical of "The Sound of Music".
