The evening was in aid of the Henry van Straubenzee Memorial Fund, set up in memory of a friend of Princes William and Harry who died in a car crash in 2002, aged 18.

The Princes, who became joint patrons of the fund in January, were not present but several of their friends were, including Guy Pelly, the actress/model Isabella Calthorpe and Astrid Harbord, who is said to have been close to Prince Harry following his break-up with Miss Davy.
