Practicing for a flash mob to promote the Choir's show.

"The show is called "Don't Stop Believing, the music of Glee," said John Dalton a member of the Choir.

A modern way for them to let people know about their modern performance.

"It's unique it's different and doesn't happen all the time. I think people will be surprised," said Dalton.

The group quietly gathers in Wichita’s Old Town Square and begins.

Surprising onlookers as they gather around with cell phones and cameras to record the whole thing.

"That was so fun, you see it on YouTube all the time but to see it in real life is special," said one onlooker.

A unique way for the members of the choir to promote a unique show.

"It went so well, we had so many people show up, it was incredible," said Matt Struika, the choreographer.

The Heart of America Men's Chorus will perform April 2nd and 3rd at the Plymoth Congregational Church Saturday 7pm Sunday 4pm.
