The singer is currently touring Russia, Rossiiskaya Gazeta said. The tour dedicated to the 60th anniversary of Victory in the Great Patriotic War (1941-1945) covers 7 Russian cities, Tula, Smolensk, Volgograd, Krasnoyarsk, Novosibirsk, Yekaterinburg, and St. Petersburg.
Khvorostovsky sang war songs to the accompaniment of the National Symphony Orchestra conducted by Konstantin Orbelyan and the UNESCO World Youth Choir comprising disabled children.
The stage was brought from Red Square, Moscow, where the singer gave a concert on May 9.
According to Khvorostovsky, the idea of this charity tour belongs to Russian President Vladimir Putin.
"I regard this both as a civil and creative act. Such concerts are unique - children are singing on the stage and WWII veterans are listening to them. This is an incredible unity of generations," the singer said at a press conference in Volgograd.
Volgograd (former Stalingrad) which sustained great losses during the war should always remember those days, the singer said. The battle of Stalingrad (1943) marked the beginning of the radical turn in World War II.
