Thirty students and parents from Renton’s Spotlight Dance and Performing Arts Center will perform at the opening ceremony Saturday of the celebration marking the 50th Anniversary of the Seattle’s World Fair.

Rehearsal directors have visited the dance studio on Tobin Street to teach the Chair Spectacle, a 30-minute piece by the Pat Graney Company that will be performed in and around the International Festival at the Seattle Center in downtown Seattle.

The Next Fifty is a six-month celebration of the impact, the memories and the legacy of the 1962 World’s Fair. Pat Graney of the Pat Graney Company visited the Renton dance studio to observe a rehearsal.

The Chair Spectacle will feature 100 people dressed in white, moving in unison on and around white chairs in the International Fountain, forming a “movement choir” and accompanied by actual recorded sounds from the 1962 World’s Fair.

There will be two performances – one at the opening ceremony on Saturday and one at the closing ceremony in October.

The Spotlight Dance & Performing Arts Center has four performing companies, with students as young as 5, who frequently perform in and around Renton. The dancers will perform at the Spring Festival at the Piazza in downtown Renton in May.
