"American Idol" Constantine Maroulis will take the stage twice during Opa Fest 2007, "A Night in Athens," on the grounds of St. Nicholas Greek Orthodox Church in Troy, the Royal Oak Daily Tribune informs.

The event runs Friday through Sunday, June 22-24. Maroulis will perform for free at 7 p.m. Saturday and 3 p.m. Sunday. This year, about 10,000 people in three days are expected to attend the festival at the church at 760 W. Wattles Road in Troy.

For the first time, a Greek folk art exhibit will be on display. Also, a variety of Greek wines will be available in the wine-tasting area. A Greek marketplace will be open to shoppers. Games and rides will be available for children.

Festival attendees are welcome to tour the church building, which contains murals and iconography saved from the original Detroit church built in the 1930s.

"The church tours are nice because they introduce people to Eastern orthodox faith," Nikitas said. "People can learn something as well as enjoy a great party."
