Music

I just saw this film last night, and besides being a wonderful film, I really enjoyed the music.

However, I don't know one of the songs that the girls sang during the film. It took place during one of their dinners when the school's matron announced that their teacher had been engaged to wed the night before. All the girls danced around their teacher singing a beautiful song.

Does anyone know the name of that song? It sounded up-beat and happy and I just loved it!
