On the second day of the Mormon Tabernacle Choir and Orchestra at Temple Square’s East Coast tour, choir and orchestra members visited Colonial Williamsburg’s historic area, where they surprised spectators with a lyrical flashmob.

Christian Smith is a bassoon player with the orchestra who stood by as first one choir member, then two, then many, and eventually all began singing “Free States” to the tune of “My Country ‘Tis of Thee.”

“The sound of the choir just enveloped everyone,” he said. “I could see expressions of confusion and just disbelief. … In the end, it was just a good feeling, and I think people were generally delighted with having been there.”

Following the two performances, senior vice president of the Colonial Williamsburg Foundation John Bacon announced, “You’ve just participated in a live performance with the world-renowned Mormon Tabernacle Choir.”

Estimates place the number of people in attendance at around 2,000.
