It was the 310th anniversary of the founding of St. Petersburg, Russia over the weekend, and to celebrate, a lot of people decided to get together and sing.
In all, 4,335 people gathered at the walls of St. Isaac's Cathedral wearing colourful raincoats, and proceeded to try and break the world record for largest choir.
The event was called 'A World of Boundless Enthusiasm', and it featured singers of all ages, with members of almost all St. Petersburg's professional and amateur choirs.
In order to qualify as a world record, the choir had to perform one song lasting at least five minutes, or two songs with no more than 10 minutes between them, according to Yuri Svetov, chairman of the Guinness World Records Audit Commission.
Not really a problem in this case: the crowd sang for a full hour, performing 14 songs, including some popular patriotic pieces from Russian and Soviet history.
So far, Guinness hasn't given word on whether the record is official, but Svetov did tell RIA Novosti "the conditions were met."
The crowd was accompanied by a symphony orchestra conducted by Vladislav Chernushenko, the "People's Artist of the USSR" and director of the St. Petersburg State Capella Symphony Orchestra.
If you've got an hour, and you'd like to hear some Russian classics as sung by a lot of damp, enthusiastic people, here's a video of the full performance.
