I really enjoyed this...

"Starting with a single cellist on the floor of the National Air and Space Museum's "Milestones of Flight" gallery, and swelling to 120 musicians, The U.S. Air Force Band exhilarated museum visitors with its first ever flash-mob. The four minute performance featured an original arrangement led by the band's commander and conductor, Col. Larry H. Lang. Unsuspecting museum visitors including tourists and school groups were astonished as instrumentalists streamed into the gallery from behind airplanes, space capsules, and vocalists burst into song from the Museum's second floor balcony."
That was really nice Pablo, thanks for posting it. I doubt I would have seen it otherwise.
You could see that it really made people happy in some of the shots, even a few people seamed momentarily overwhelmed. That is quite nice.
Wonderful experience it must have been!
Great!
