Mother and son, Monica and Patrick Anderson perform a waltz before switching to a hip hop dance routine during a rehearsal for the World Dance Extravaganza at The Overlake School last Friday. There were two performances last Saturday open to the community and showcased 72-80 performers, including students, in dances from Cambodia, the Philippines, East Africa, Eastern Europe, the Americas, India, Pakistan, the Silk Route countries of Central Asia and the Middle East. Twenty-two of the dancers were faculty, staff or parents, with the fifth-graders performing a special dance.
