A evening pause: This is almost a real flash mob event at the Air & Space Museum. It seems as if they sneak up on the holiday crowds, but at the same time I am not so sure. Too many cameraman around, as well as performers. Regardless, it is a great performance.
Hat tip Edward Thelen, and Tim Vogel (who suggested this a couple of years ago when I was especially dismissive of fake flash mob events. Since then I’ve mellowed). Also, as Edward notes, the schedule of events at the end of this video no longer applies.
