A Nashville swingers club has transformed itself into a church after neighbors blocked it from opening next to a suburban Christian school. Now it's challenging the city to prove it's not a legitimate house of worship.

The president of Goodpasture Christian School received an anonymous tip about the club in November. He worked with religious leaders and the Metro Council to block it from opening.

That's when The Social Club became the United Fellowship Center. On the new plans, a room previously labeled "dungeon" is now labeled "choir."

Attorney Larry Roberts represents the club-turned-church. He says no sex will take place there, but opponents are skeptical.

Zoning officials say they can't prevent it from opening. But if it doesn't operate as a church, they can shut it down.
