Albeit with significant alteration, the original Louis Armstrong and Grandstand stadiums at the U.S. Open were divided from the Singer Bowl, a stadium constructed by the Singer Sewing Company for the 1964 World’s Fair. After the World’s Fair, it was used for hosting concerts, Olympic trials, and professional boxing events. The Doors, The Who, and Jimi Hendrix performed there, while the Mets had a fireworks display on premise to celebrate the 1969 World Series win.
