Russian biathletes decided to sing their national anthem without any instrumental accompaniment after organisers played an outdated version in an embarrassing medal ceremony at the biathlon world championships.
The ceremony was interrupted when it became clear the old version of the anthem was being used to honour Russia's victory in Saturday night's 4x7.5-kilometre relay.
However, Alexey Volkov, Maxim Tsvetkov, Anton Babikov and Anton Shipulin didn't wait for the correct version to be played and started singing their national anthem unaccompanied.
The incident came just one week after the United States Tennis Association had to apologise after an outdated version of the German national anthem was performed before a Fed Cup quarter-final match in Hawaii.
