The Royal Ballet’s sizeable Japanese contingent of dancers, headed by former principal ballerina Miyako Yoshida, are staging a concert performance of ballet at 4pm today in aid of the Japanese Tsunami Appeal. All tickets are £20, to pay in cash on the door at arrival at the Linbury Studio Theatre, Royal Opera House. Yoshida, former Principal, hopes to be joined on stage by Yuhui Choe, Valeri Hristov, Hikaru Kobayashi, Ryoichi Hirano, Kenta Kura, Akane Takada and students from the Royal Academy of Music for the hour-long show.
