The Royal Ballet’s founder choreographer, Frederick Ashton, followed a similar strategy, leaving his ballets to his friends in the hope that they could make a bit of money out of them. This policy served him well when the ballets lay in the hands of the people who danced them, such as Michael Somes, Margot Fonteyn and Brian Shaw. But the death of Alexander Grant last week is a reminder of its perils: he owned La Fille mal gardée, one of Ashton’s greatest works. No one knows who will be left it in his will. Once the works pass out of the hands of dancers who understand Ashton’s legacy, they are in need of extra care.
