If you had actually watched anything other than the dub, you'd know that the song in the trailer is one of the endings about a kid and a woman singing about wanting to grow up and become a kid again respectively, and considering the woman in the trailer even appears in the movie with the same voice as in the song, it's pretty obvious they just represent the ones singing.
