Unsuspecting Chick-fil-A customers met with flash mob of worship music

Along with their chicken sandwiches, customers at a Nashville Chick-fil-A on Saturday received a side of Christian music from a flash mob that broke out among a capella worship leaders.

Before long, a video of the performance was viewed at least 8 million times.

It's the third straight year members from Nashville's Worship Leader Institute conference started a flash mob inside the Chick-Fil-A restaurant, a performance supported by the restaurant manager, according to Fox 5 Atlanta.

This year, the group sang Hezekiah Walker's "Every Praise." It started with just one table singing, and as the song progressed, more groups of people with the conference began getting involved.

Video of the flash mob, shared on Facebook by part-time worship minister Chris Armstead, of Atlanta, has been viewed 8.1 million times and shared more than 180,000 times since Saturday.

"The first group, including the leader, began the flash mob by standing up to start the song at their table, and then the other groups stood in succession at their tables/booths to join into the song at predefined times until all 60+ guys were singing the song," Armstead told Fox 5.

Armstead said customers and Chick-fil-A employees joined in to sing as well.
