I really like that one but my favourite orchestral flash mob has to be:
The Copenhagen Phil is a great orchestra, but I think they could have picked a better song than Bolero for a flash exibit.
On another note, Denmark was one of my favorite countries I've been to. I was at Aalborg for 43 days and had a blast. Two things I learned while there. 1. The Danes love to party. 2. There were more beautiful blond haired, blue eyed women than I could shake a stick (or anything else) at.
And Aalborg was/is such a beautiful city. Everything was clean and beautifully landscaped. At the time I was there, the people were really fond of Americans, for the most part anyway. They've probably wised up by now. lol
