Turns out the Country Playhouse has more than 100 volunteers from the community participating in this 'impromptu' event to promote Hairspray, which just so happens to be the next production at the Country Playhouse.
I'm told the flash mob will perform three times. Twice Thursday night: 7pm at Memorial City Mall (near the skating rink) and 8pm at City Center (on the green, in the front of Yardhouse and Ruggles). The third time will be on stage at the Country Playhouse before the production of Hairspray on July 15th.
