Did you perhaps see a bunch of "single ladies" dancing downtown on Saturday?
The Beyonce flash mob brought out the dancer in about 50 people as they moved through a choreographed dance to a four-part medley of "Crazy In Love," "Get Me Bodied," "Run The World (Girls)," and of course, "Single Ladies." Dancing through downtown, the Ferry Building plaza, and Union Square, the flash mob caught the attention of tourists and locals alike, inciting cheers and camera phone snapshots.
Check out the flash mob practice session and Castro performance:
