The newlyweds were completely taken by surprise as one-by-one their wedding guests stood up during their wedding reception in Copenhagen and burst into song. They sang "One Day More" from the musical Les Miserables.
Since this video hit the web in May, shot at the wedding reception of Danish couple Susanne and Sune Vibæk Svanekier, hundreds of thousands of people have seen it and it's still catching fire. The new Les Miserables movie certainly doesn't hurt!
Here's the trailer for the movie, which comes out Christmas Day.
