A joint charity concert they are giving tonight in Ufa has trawled in a phenomenal 30 million rubles.
Hvorostovsky has undergone treatment this year for brain cancer.
Ildar Abdrazakov said: ‘Last year a similar concert in Moscow, in the Kremlin, made 20 million rubles. In Ufa, we have raised half as much again – 30 million. I am so proud of my compatriots, and this not the final figure.’
