Hello here too. :) I already said sorry for you on the french musicals community, but I followed you here and read this post too, sorry. :)

So about the missings songs: there are 4 songs on the CD integrale which are not in the show, because of time constraints. For a while it was considered to put L'opérarap back into the show during the Tournée, but it seems it's still out, so as the other 3 songs.
