Mama Mia is set on a fictional Greek Island. Though there not much of a Greek feel to the show and the subject matter may not be right for you.
The Frogs is a musical "freely adapted" by Stephen Sondheim and Burt Shevelove from The Frogs, an Ancient Greek comedy by Aristophanes.
Xanadu (2007) is a musical comedy about the Greek Muses; based on the 1980 film. Book by Douglas Carter Beane and music and lyrics by Jeff Lynne and John Farrar. It does involve roller skating.
Although not set in Greece,
Legally Blonde uses the sorority sisters of Delta Nu as a Greek chorus.
Tales of Olympus: A Greek Myth Musical. Book, music & lyrics by Min Kahng; commissioned by Bay Area Children's Theatre (Oakland, CA).
Peering down from their home on Mt. Olympus, the ancient Greek gods see a fast-paced, modern world filled with high-tech distractions. Who has the time to remember their stories? Calliope, the goddess of epic poetry, descends from the mountaintop to enlist the help of an 11-year-old mortal, Jason. But does Jason have the guts to overcome his stage fright and become the next bard?

Subject: Musical set in Greece
I am at a k-8 school, and our middle school is travelling to Greece next year! My admin asked if I could tailor the Spring Musical to match the trip. I will order the perusal of Xanadu, Jr., but I was wondering if there are any other musicals that are either set in Greece or deal with Greek mythology. It has to be appropriate for k-8, so no Mamma Mia!
