If a bride's wedding is the happiest day of her life, and Disneyland is the happiest place on earth, then what does that make a wedding at Disneyland? Pretty amazing, according to this video.

The wedding looks like something out of a Disney movie, including the bride's arrival in Cinderella's carriage to say "I do" in front of her castle.

But the most glamorous part of the ceremony was one the bride didn't even know about until she saw it herself: Disney arranged for Pentatonix to be her wedding band.

The surprise performance was captured as part of the Disney's Fairy Tale Weddings special, which showed how the theme park makes their guests' dream weddings come true.

Ruby and Eric, the couple in this video, had a glamorous wedding on Main Street USA after hours, which could cost as much as $12,000 (including a cake, catering and flowers).

For couples on a budget, a wedding in the Magic Kingdom or on a Disney Cruise could start at just $2,500.

But hiring Pentatonix to sing "Hallelujah" as you walk down the aisle is too expensive for just about everyone.

Their performance of Leonard Cohen's classic song shows why fans love this group. Hearing their voices just sends chills down your spine, especially during a special moment like this.

The band is touring Japan right now, but they'll be back in America soon, so grab your tickets if you want to see them live.
