In 1966 the U.S. Open was held at the Seattle World's Fair Grounds. The Beatles were on hand to give a concert. At the Open the tournament director drew the curtains over the playing hall. The hundreds of Beatle fans, seeing the hall shrouded by the drapes, assumed the Beatles were inside. They began pounding on the windows until someone opened the drapes to reveal a chess tournament was taking place. Ringo Starr and John Lennon played chess. Yoko Ono also plays chess.
