So in the opening number we had to introduce the audience to the world of the show, the characters, and something we didn't have in the film, the chorus. On Broadway a big tool is the ensemble and the biggest thing you can do in a Broadway musical is have everyone in the ensemble sing, whereas in a movie lots of other things are a bigger deal than that. You have action, you have close-ups, you have, you know, catastrophe, explosions, all that stuff. On Broadway the biggest thing you can do is stand there and sing out to the audience, and that's what we wanted to make sure we did. We wanted everybody to fall in love with Arendelle and the town. So we didn't know exactly what it was going to be, but we arrived, we wanted to use the Scandinavian... Opening from the film. Right. We wanted to begin with Vueli, which is written by another composer, Frode Fjellheim and Christoph Beck, who wrote the music for all the film score of Frozen. And so we begin with that, and then we segue into the little girl singing, Do You Want to Build a Snowman? Because we wanted the audience... The reason for that was that it was very important in Denver, we realized, to tell the audience they will hear the songs that they like from the movie. And because of how we're telling the story, we weren't going to hear another familiar tune all the way until Do You Want to Build a Snowman? About 10 minutes into the musical at that point. So we needed to say, you know that tune you know? We're putting it up here. And we also needed to kind of iris in on, this is who we will be watching all night, the two little girls. It was during rehearsals for Broadway that we realized the song that we had, which was called The Story of a Family, wasn't enough to really begin the story. We needed something more emotional, and we came up with Let the Sun Shine On. We rewrote that number in previews, a week into previews, we wrote that. Wasn't it? No, it was... The end of rehearsal. It was the end of rehearsal. We had gotten to tech, and we realized we needed a different tune for the mini opening number. But it isn't a real opening number exactly. No. Because the real opening number is First Time in Forever, which is at minute 12. So this was something for this particular production, we needed to have an opening number that felt opening number enough, but did not take away from the real opening number when we have grown up girls and we're really into the story.
