The Russian President was mid-sentence when a state broadcast cut to patriotic songs – prompting confusion among audiences.
He was speaking in front of 100,000 supporters at Moscow’s Luzhniki Stadium when the feed cut out and began playing a concert by singer and composer Oleg Gazmanov.
Just poor editing on behalf of the broadcast. In reality, his speech has not been cut by any means, it was just edited out when Putin started to talk about Admiral Ushakov.
Refer to 1:56 and beyond.
