“I live in Switzerland but I pay my taxes in France. I don’t know the exact extent of my fortune because I am not a businessman. For a gala concert, I get 60,000 euros. If I need money, I go to Abu Dhabi or Japan, where I can get 100,000 euros. I get 25 centimes for every CD sale, but I don’t get anything for DVDs or broadcasts or cinema transmissions. …. In the opera house, I get roughly 13,000 euros a performance.”
