Flash mob flashes back to Woodstock

Sunday summer afternoons in Union Square settle into a distinctly European rhythm. It’s time for cappuccino, gelato and wine chilling in buckets; time to find a good sideline seat and watch the crowd of tourists and shoppers spill over into the streets.

So imagine the surprise yesterday – 40 years to the day after The Who played “Tommy” at Woodstock – when a flash mob of nearly 100 dancers took over the square for a full-tilt run through “Pinball Wizard.”
