Balthus, the highly respected realist painter of often erotic work, was buried today in the Swiss village close to the chalet were he spent the last 23 years of his life.
Bono sang for some 350 mourners including French photographer Henri Cartier-Bresson, Prince Sadruddin Aga Khan and Australian supermodel Elle McPherson.
The French, Italian and Swiss governments also sent representatives to the church ceremony in honour of the enigmatic painter who is among the few to have his works exhibited in the Louvre museum in Paris while still alive.
Balthus was known for his provocative paintings of young women, often with surreal elements in the background.
The atmosphere of his work has been compared to the ambiance evoked by the books of French writer Marcel Proust.
