On 14 March 2020 I was at Leeds Grand Theatre for the première of Northern Ballet’s Geisha. The curtains swung open on fishermen flinging out their nets, geisha, samurai, 19th-century Japanese village folk, followed by the sudden appearance of American sailors. It was in essence a Japanese Giselle: the tale of a geisha, spurned by her American lover, who dies of grief, and whose restless spirit returns from the grave.
